Make the code like the rest of the kernel.
Also use inline instead of __inline__.

Linus Torvalds 6481352082 USB fixes for 4.13-rc1
Here are some remaining USB fixes for 4.13-rc1.  They were originally
 scheduled for 4.12-final, but I didn't send them to you in time.
 Because of that, they were in a separate branch from the larger USB set
 of patches, so here they are in a separate pull request.
 
 Nothing major here a all, just 3 small patches:
 	- some usb-serial new device ids
 	- xhci bugfix for some crazy AMD hardware
 
 All of these have been in linux-next for a long time with no reported
 issues.

Pull misc compat stuff updates from Al Viro:
 "This part is basically untangling various compat stuff. Compat
  syscalls moved to their native counterparts, getting rid of quite a
  bit of double-copying and/or set_fs() uses. A lot of field-by-field
  copyin/copyout killed off.

   - kernel/compat.c is much closer to containing just the
     copyin/copyout of compat structs. Not all compat syscalls are gone
     from it yet, but it's getting there.

   - ipc/compat_mq.c killed off completely.

   - block/compat_ioctl.c cleaned up; floppy compat ioctls moved to
     drivers/block/floppy.c where they belong. Yes, there are several
     drivers that implement some of the same ioctls. Some are m68k and

Linus Torvalds 920f2ecdf6 sound updates for 4.13-rc1
This development cycle resulted in a fair amount of changes in both
 core and driver sides.  The most significant change in ALSA core is
 about PCM.  Also the support of of-graph card and the new DAPM widget
 for DSP are noteworthy changes in ASoC core.  And there're lots of
 small changes splat over the tree, as you can see in diffstat.
 
 Below are a few highlights:
 
 ALSA core:
 - Removal of set_fs() hackery from PCM core stuff, and the code
   reorganization / optimization thereafter
 - Improved support of PCM ack ops, and a new ABI for improved
   control/status mmap handling
 - Lots of constifications in various codes
 
 ASoC core:
 - The support of of-graph card, which may work as a better generic
   device for a replacement of simple-card
 - New widget types intended mainly for use with DSPs
 
 ASoC drivers:
 - New drivers for Allwinner V3s SoCs
 - Ensonic ES8316 codec support
 - More Intel SKL and KBL works
 - More device support for Intel SST Atom (mostly for cheap tablets and
   2-in-1 devices)
 - Support for Rockchip PDM controllers
 - Support for STM32 I2S and S/PDIF controllers
 - Support for ZTE AUD96P22 codecs
 
 HD-audio:
 - Support of new Realtek codecs (ALC215/ALC285/ALC289), more quirks
   for HP and Dell machines
 - A few more fixes for i915 component binding
 
 Note that of-graph change may bring the conflicts with a later pull
 request of devicetree, as currently found in linux-next.

Linus Torvalds 408c9861c6 Power management updates for v4.13-rc1
- Rework suspend-to-idle to allow it to take wakeup events signaled
    by the EC into account on ACPI-based platforms in order to properly
    support power button wakeup from suspend-to-idle on recent Dell
    laptops (Rafael Wysocki).
 
    That includes the core suspend-to-idle code rework, support for
    the Low Power S0 _DSM interface, and support for the ACPI INT0002
    Virtual GPIO device from Hans de Goede (required for USB keyboard
    wakeup from suspend-to-idle to work on some machines).
 
  - Stop trying to export the current CPU frequency via /proc/cpuinfo
    on x86 as that is inaccurate and confusing (Len Brown).
 
  - Rework the way in which the current CPU frequency is exported by
    the kernel (over the cpufreq sysfs interface) on x86 systems with
    the APERF and MPERF registers by always using values read from
    these registers, when available, to compute the current frequency
    regardless of which cpufreq driver is in use (Len Brown).
 
  - Rework the PCI/ACPI device wakeup infrastructure to remove the
    questionable and artificial distinction between "devices that
    can wake up the system from sleep states" and "devices that can
    generate wakeup signals in the working state" from it, which
    allows the code to be simplified quite a bit (Rafael Wysocki).
 
  - Fix the wakeup IRQ framework by making it use SRCU instead of
    RCU which doesn't allow sleeping in the read-side critical
    sections, but which in turn is expected to be allowed by the
    IRQ bus locking infrastructure (Thomas Gleixner).
 
  - Modify some computations in the intel_pstate driver to avoid
    rounding errors resulting from them (Srinivas Pandruvada).
 
  - Reduce the overhead of the intel_pstate driver in the HWP
    (hardware-managed P-states) mode and when the "performance"
    P-state selection algorithm is in use by making it avoid
    registering scheduler callbacks in those cases (Len Brown).
 
  - Rework the energy_performance_preference sysfs knob in
    intel_pstate by changing the values that correspond to
    different symbolic hint names used by it (Len Brown).
 
  - Make it possible to use more than one cpuidle driver at the same
    time on ARM (Daniel Lezcano).
 
  - Make it possible to prevent the cpuidle menu governor from using
    the 0 state by disabling it via sysfs (Nicholas Piggin).
 
  - Add support for FFH (Fixed Functional Hardware) MWAIT in ACPI C1
    on AMD systems (Yazen Ghannam).
 
  - Make the CPPC cpufreq driver take the lowest nonlinear performance
    information into account (Prashanth Prakash).
 
  - Add support for hi3660 to the cpufreq-dt driver, fix the
    imx6q driver and clean up the sfi, exynos5440 and intel_pstate
    drivers (Colin Ian King, Krzysztof Kozlowski, Octavian Purdila,
    Rafael Wysocki, Tao Wang).
 
  - Fix a few minor issues in the generic power domains (genpd)
    framework and clean it up somewhat (Krzysztof Kozlowski,
    Mikko Perttunen, Viresh Kumar).
 
  - Fix a couple of minor issues in the operating performance points
    (OPP) framework and clean it up somewhat (Viresh Kumar).
 
  - Fix a CONFIG dependency in the hibernation core and clean it up
    slightly (Balbir Singh, Arvind Yadav, BaoJun Luo).
 
  - Add rk3228 support to the rockchip-io adaptive voltage scaling
    (AVS) driver (David Wu).
 
  - Fix an incorrect bit shift operation in the RAPL power capping
    driver (Adam Lessnau).
 
  - Add support for the EPP field in the HWP (hardware managed
    P-states) control register, HWP.EPP, to the x86_energy_perf_policy
    tool and update msr-index.h with HWP.EPP values (Len Brown).
 
  - Fix some minor issues in the turbostat tool (Len Brown).
 
  - Add support for AMD family 0x17 CPUs to the cpupower tool and fix
    a minor issue in it (Sherry Hurwitz).
 
  - Assorted cleanups, mostly related to the constification of some
    data structures (Arvind Yadav, Joe Perches, Kees Cook, Krzysztof
    Kozlowski).

     wake up the system from sleep states" and "devices that can
     generate wakeup signals in the working state" from it, which allows
     the code to be simplified quite a bit (Rafael Wysocki).

   - Fix the wakeup IRQ framework by making it use SRCU instead of RCU
     which doesn't allow sleeping in the read-side critical sections,
     but which in turn is expected to be allowed by the IRQ bus locking
     infrastructure (Thomas Gleixner).

   - Modify some computations in the intel_pstate driver to avoid
     rounding errors resulting from them (Srinivas Pandruvada).

   - Reduce the overhead of the intel_pstate driver in the HWP
     (hardware-managed P-states) mode and when the "performance" P-state
     selection algorithm is in use by making it avoid registering
     scheduler callbacks in those cases (Len Brown).

   - Rework the energy_performance_preference sysfs knob in intel_pstate
     by changing the values that correspond to different symbolic hint
     names used by it (Len Brown).

   - Make it possible to use more than one cpuidle driver at the same
     time on ARM (Daniel Lezcano).

   - Make it possible to prevent the cpuidle menu governor from using
     the 0 state by disabling it via sysfs (Nicholas Piggin).

   - Add support for FFH (Fixed Functional Hardware) MWAIT in ACPI C1 on
     AMD systems (Yazen Ghannam).

   - Make the CPPC cpufreq driver take the lowest nonlinear performance
     information into account (Prashanth Prakash).

   - Add support for hi3660 to the cpufreq-dt driver, fix the imx6q
     driver and clean up the sfi, exynos5440 and intel_pstate drivers
     (Colin Ian King, Krzysztof Kozlowski, Octavian Purdila, Rafael
     Wysocki, Tao Wang).

   - Fix a few minor issues in the generic power domains (genpd)
     framework and clean it up somewhat (Krzysztof Kozlowski, Mikko
     Perttunen, Viresh Kumar).

   - Fix a couple of minor issues in the operating performance points
     (OPP) framework and clean it up somewhat (Viresh Kumar).

   - Fix a CONFIG dependency in the hibernation core and clean it up
     slightly (Balbir Singh, Arvind Yadav, BaoJun Luo).

   - Add rk3228 support to the rockchip-io adaptive voltage scaling
     (AVS) driver (David Wu).

   - Fix an incorrect bit shift operation in the RAPL power capping
     driver (Adam Lessnau).

   - Add support for the EPP field in the HWP (hardware managed
     P-states) control register, HWP.EPP, to the x86_energy_perf_policy
     tool and update msr-index.h with HWP.EPP values (Len Brown).

   - Fix some minor issues in the turbostat tool (Len Brown).

   - Add support for AMD family 0x17 CPUs to the cpupower tool and fix a
     minor issue in it (Sherry Hurwitz).

   - Assorted cleanups, mostly related to the constification of some
     data structures (Arvind Yadav, Joe Perches, Kees Cook, Krzysztof
     Kozlowski)"

Linus Torvalds 974668417b driver core patches for 4.13-rc1
Here is the big driver core update for 4.13-rc1.
 
 The large majority of this is a lot of cleanup of old fields in the
 driver core structures and their remaining usages in random drivers.
 All of those fixes have been reviewed by the various subsystem
 maintainers.  There's also some small firmware updates in here, a new
 kobject uevent api interface that makes userspace interaction easier,
 and a few other minor things.
 
 All of these have been in linux-next for a long while with no reported

Devin Heitmueller 6836796de4 Add USB quirk for HVR-950q to avoid intermittent device resets
The USB core and sysfs will attempt to enumerate certain parameters
which are unsupported by the au0828 - causing inconsistent behavior
and sometimes causing the chip to reset.  Avoid making these calls.

This problem manifested as intermittent cases where the au8522 would
be reset on analog video startup, in particular when starting up ALSA
audio streaming in parallel - the sysfs entries created by
snd-usb-audio on streaming startup would result in unsupported control
messages being sent during tuning which would put the chip into an
unknown state.

Rafael J. Wysocki de3ef1eb1c PM / core: Drop run_wake flag from struct dev_pm_info
The run_wake flag in struct dev_pm_info is used to indicate whether
or not the device is capable of generating remote wakeup signals at
run time (or in the system working state), but the distinction
between runtime remote wakeup and system wakeup signaling has always
been rather artificial.  The only practical reason for it to exist
at the core level was that ACPI and PCI treated those two cases
differently, but that's not the case any more after recent changes.

For this reason, get rid of the run_wake flag and, when applicable,
use device_set_wakeup_capable() and device_can_wakeup() instead of
device_set_run_wake() and device_run_wake(), respectively.

Heikki Krogerus c1b0bc2dab usb: typec: Add support for UCSI interface
UCSI - USB Type-C Connector System Software Interface - is a
specification that defines set of registers and data
structures for controlling the USB Type-C ports. It's
designed for systems where an embedded controller (EC) is in
charge of the USB Type-C PHY or USB Power Delivery
controller. It is designed for systems with EC, but it is
not limited to them, and for example some USB Power Delivery
controllers will use it as their direct control interface.

With UCSI the EC (or USB PD controller) acts as the port
manager, implementing all USB Type-C and Power Delivery state
machines. The OS can use the interfaces for reading the
status of the ports and controlling basic operations like
role swapping.

The UCSI specification highlights the fact that it does not
define the interface method (PCI/I2C/ACPI/etc.).
Therefore the driver is implemented as library and every
supported interface method needs its own driver. Driver for
ACPI is provided in separate patch following this one.

The initial driver includes support for all required
features from UCSI specification version 1.0 (getting
connector capabilities and status, and support for power and
data role swapping), but none of the optional UCSI features
(alternate modes, power source capabilities, and cable
capabilities).

Kuppuswamy Sathyanarayanan 57129044f5 mfd: intel_soc_pmic_bxtwc: Use chained IRQs for second level IRQ chips
Whishkey cove PMIC has support to mask/unmask interrupts at two levels.
At first level we can mask/unmask interrupt domains like TMU, GPIO, ADC,
CHGR, BCU THERMAL and PWRBTN and at second level, it provides facility
to mask/unmask individual interrupts belong each of this domain. For
example, in case of TMU, at first level we have TMU interrupt domain,
and at second level we have two interrupts, wake alarm, system alarm that
belong to the TMU interrupt domain.

Currently, in this driver all first level IRQs are registered as part of
IRQ chip(bxtwc_regmap_irq_chip). By default, after you register the IRQ
chip from your driver, all IRQs in that chip will masked and can only be
enabled if that IRQ is requested using request_irq() call. This is the
default Linux IRQ behavior model. And whenever a dependent device that
belongs to PMIC requests only the second level IRQ and not explicitly
unmask the first level IRQ, then in essence the second level IRQ will
still be disabled. For example, if TMU device driver request wake_alarm
IRQ and not explicitly unmask TMU level 1 IRQ then according to the default
Linux IRQ model,  wake_alarm IRQ will still be disabled. So the proper
solution to fix this issue is to use the chained IRQ chip concept. We
should chain all the second level chip IRQs to the corresponding first
level IRQ. To do this, we need to create separate IRQ chips for every
group of second level IRQs.

In case of TMU, when adding second level IRQ chip, instead of using PMIC
IRQ we should use the corresponding first level IRQ. So the following
code will change from

ret = regmap_add_irq_chip(pmic->regmap, pmic->irq, ...)

to,

virq = regmap_irq_get_virq(&pmic->irq_chip_data, BXTWC_TMU_LVL1_IRQ);

ret = regmap_add_irq_chip(pmic->regmap, virq, ...)

In case of Whiskey Cove Type-C driver, Since USBC IRQ is moved under
charger level2 IRQ chip. We should use charger IRQ chip(irq_chip_data_chgr)
to get the USBC virtual IRQ number.

Ruslan Bilovol 0591bc2360 usb: gadget: add f_uac1 variant based on a new u_audio api
This patch adds a new function 'f_uac1'
(f_uac1 with virtual "ALSA card") that
uses recently created u_audio API. Comparing
to legacy f_uac1 function implementation it
doesn't require any real Audio codec to be
present on the device. In f_uac1 audio
streams are simply sinked to and sourced
from a virtual ALSA sound card created
using u_audio API.

Legacy f_uac1 approach is to write audio
samples directly to existing ALSA sound
card

f_uac1 approach is more generic/flexible
one - create an ALSA sound card that
represents USB Audio function and allows to
be used by userspace application that
may choose to do whatever it wants with the
data received from the USB Host and choose
to provide whatever it wants as audio data
to the USB Host.

f_uac1 also has capture support (gadget->host)
thanks to easy implementation via u_audio.
By default, capture interface has 48000kHz/2ch
configuration, same as playback channel has.

f_uac1 descriptors naming convention
uses f_uac2 driver naming convention that
makes it more common and meaningful.

Comparing to f_uac1_legacy, the f_uac1 doesn't
have volume/mute functionality. This is because
the f_uac1 volume/mute feature unit was dummy
implementation since that driver creation (2009)
and never had any real volume control or mute
functionality, so there is no any difference
here.

Since f_uac1 functionality, exposed
interface to userspace (virtual ALSA card),
input parameters are so different comparing
to f_uac1_legacy, that there is no any
reason to keep them in the same file/module,
and separate function was created.

g_audio can be built using one of existing
UAC functions (f_uac1, f_uac1_legacy or f_uac2)

Ruslan Bilovol 7158b57a49 usb: gadget: f_uac2: remove platform driver/device creation
Simplify f_uac2 by removing platform driver/device
creation; use composite's usb_gadget device as
parent for sound card and for debug prints.
This removes extra layer of code without any functional
change.

Ruslan Bilovol 1fc4926d92 usb: gadget: function: f_uac1: implement get_alt()
After commit 7e4da3fcf7 ("usb: gadget: composite:
Test get_alt() presence instead of set_alt()") f_uac1
function became broken because it doesn't have
get_alt() callback implementation and composite
framework never set altsetting 1 for audiostreaming
interface. On host site it looks like:

 [424339.017711] 21:1:1: usb_set_interface failed (-32)

Since host can't set altsetting 1, it can't start
playing audio.

In order to fix it implemented get_alt along with
minor improvements (error conditions checking)
similar to what existing f_uac2 has.
