Linus Torvalds d0a3997c0c sound updates for 4.1-rc1
There have been major modernization with the standard bus: in ALSA
 sequencer core and HD-audio.  Also, HD-audio receives the regmap
 support replacing the in-house cache register cache code.  These
 changes shouldn't impact the existing behavior, but rather
 refactoring.
 
 In addition, HD-audio got the code split to a core library part and
 the "legacy" driver parts.  This is a preliminary work for adapting
 the upcoming ASoC HD-audio driver, and the whole transition is still
 work in progress, likely finished in 4.1.
 
 Along with them, there are many updates in ASoC area as usual, too:
 lots of cleanups, Intel code shuffling, etc.
 
 Here are some highlights:
 
 ALSA core:
 - PCM: the audio timestamp / wallclock enhancement
 - PCM: fixes in DPCM management
 - Fixes / cleanups of user-space control element management
 - Sequencer: modernization using the standard bus
 
 HD-audio:
 - Modernization using the standard bus
 - Regmap support
 - Use standard runtime PM for codec power saving
 - Widget-path based power-saving for IDT, VIA and Realtek codecs
 - Reorganized sysfs entries for each codec object
 - More Dell headset support
 
 ASoC:
 - Move of jack registration to the card level
 - Lots of ASoC cleanups, mainly moving things from the CODEC level
   to the card level
 - Support for DAPM routes specified by both the machine driver and DT
 - Continuing improvements to rcar
 - pcm512x enhacements
 - Intel platforms updates
 - rt5670 updates / fixes
 - New platforms / devices: some non-DSP Qualcomm platforms, Google's
   Storm platform, Maxmim MAX98925 CODECs and the Ingenic JZ4780 SoC
 
 Misc:
 - ice1724: Improved ESI W192M support
 - emu10k1: Emu 1010 fixes/enhancement

Takashi Sakamoto e1c78df1da ALSA: ctl: fix to handle several elements added by one operation for userspace element
An element instance can have several elements with the same feature.
Some userspace applications can add such an element instance by add
operation with the number of elements. Then, the element instance
gets a memory object to keep states of these elements.

But the element instance has just one memory object for the elements.
This causes the same result to each read/write operations to the
different elements.

This commit fixes this bug by allocating enough memory objects to the
element instance for each of elements.

Al Viro 1c65d98672 pcm: another weird API abuse
readv() and writev() should _not_ ignore all but the first ->iov_len,
among other things.  Really weird abuse of those syscalls - it
expects a vector element per channel, with identical lengths (it
actually assumes them to be identical - no checking is done).
readv() and writev() are really bad match for that.  Unfortunately,
userland API is userland API and we can't do anything about them.

Converted to ->read_iter/->write_iter.  Please, _please_ don't do
anything of that kind when designing new interfaces.

Takashi Sakamoto 2225e79b9b ALSA: core: reduce stack usage related to snd_ctl_new()
The callers of snd_ctl_new() need to have 'struct snd_kcontrol' data,
and pass the data as template. Then, the function allocates the structure
data again and copy from the template. This is a waste of resources.
Especially, the callers use large stack for the template.

This commit removes a need of template for the function, thus, changes
the prototype of snd_ctl_new(). Furthermore, this commit changes
the code of callers, snd_ctl_new1() and snd_ctl_elem_add() for better
shape.

An internal PCM object shouldn't be added to the PCM device list, as
it's never accessed directly from the user-space, and it has no proc

list.

Actually, the whole snd_pcm_dev_register() can be skipped for an
internal PCM.  So this patch changes the code there, but also
addresses the uninitialized list_head access.

Takashi Iwai 7c37ae5c62 ALSA: seq: Rewrite sequencer device binding with standard bus
We've used the old house-made code for binding the sequencer device
and driver.  This can be far better implemented with the standard
bus nowadays.

This patch refactors the whole sequencer binding code with the bus
/sys/bus/snd_seq.  The devices appear as id-card-device on this bus
and are bound with the drivers corresponding to the given id like the
former implementation.  The module autoload is also kept like before.

There is no change in API functions by this patch, and almost all
transitions are kept inside seq_device.c.  The proc file output will
change slightly but kept compatible as much as possible.

Further integration works will follow in later patches.

Takashi Sakamoto e6ff3840dc ALSA: control: fix failure to return new numerical ID in 'replace' event data
In 'replace' event data, numerical ID of control is always invalid. This
commit fix this bug so as the event data has renewed numerical ID for
control.

Don't use generic snapshot of trigger_tstamp if low-level driver or
hardware can get a more precise value for better audio/system time
synchronization.

Pierre-Louis Bossart 0d59b81435 ALSA: pcm: don't override timestamp unconditionally
timestamp in RUNNING mode is already taken in update_hw_ptr routine,
getting a new timestamp introduces offset between hw_ptr, audio_tstamp
and system time

Add else condition to read timestamp as fallback and only when
enabled

Takashi Sakamoto d34890cf41 ALSA: control: fix failure to return numerical ID in 'add' event
Currently when adding a new control, the assigned numerical ID is not
set for event data, thus userspace applications cannot realize it just
by event data.

Takashi Iwai 6bbc7fed84 ALSA: Add a helper to add a new attribute group to card
For assigning sysfs entries for a card device from the driver,
introduce a new helper function, snd_card_add_dev_attr().  In this
way, we can avoid the possible race between the device registration
and the sysfs addition / removal.

The driver can pass a new attribute group to add freely.  This has to
be called before snd_card_register().

Currently, up to two extra groups can be added.  More than that, it'll
return an error.
