Axel Lin 98ea5c218e regulator: Use mc13xxx_reg_write instead of mc13xxx_reg_rmw in mc13892_sw_regulator_set_voltage
Currently, we call mc13xxx_reg_read and mc13xxx_reg_rmw for the same register.
This can be converted to simply a mc13xxx_reg_read and a mc13xxx_reg_write,
thus save a redundant register read.

Mark Brown bf5892a816 regulator: Support voltage offsets to compensate for drops in system
Some systems, particularly physically large systems used for early
prototyping, may experience substantial voltage drops between the regulator
and the consumers as a result of long traces in the system. With these
systems voltages may need to be set higher than requested in order to
ensure reliable system operation.

Allow systems to work around such hardware issues by allowing constraints
to supply an offset to be applied to any requested and reported voltages.
This is not ideal, especially since the voltage drop may be load dependant,
but is sufficient for most affected systems, it is not expected to be used
in production hardware. The offset is applied after all constraint
processing so constraints should be specified in terms of consumer values
not physically configured values.

supply_regulator_dev (using a struct pointer) has been deprecated in favour
of supply_regulator (using a regulator name) for quite a few releases
now with a warning generated if it is used and there are no current in tree

Axel Lin ba413c5972 regulator: Move VCOINCELL to be the last element of mc13892_regulators array
In include/linux/mfd/mc13892.h, we define MC13892_VCOINCELL as 23.
Thus VCOINCELL should be defined as 23th element in mc13892_regulators array, not the first one.
This actually fixes an off-by-one bug while accessing mc13892_regulators array.

For example,
In mc13892_regulator_probe, we use MC13892_VCAM as array index of mc13892_regulators array.
        mc13892_regulators[MC13892_VCAM].desc.ops->set_mode
                = mc13892_vcam_set_mode;
Currently, it access mc13892_regulators[12] ,which is VAUDIO not VCAM.

Current set_mode logic does not support 6030. The logic for 4030 is
not reusable for 6030 as the mode setting for 6030 now uses the new

Saquib Herman b2456779f3 regulator: twl: fix twl6030 regulator is_enabled
With TWL6030, it is not enough to ensure that the regulator is the
group of P1 group (CPU/Linux), but we need to check the state as far
as APP is concerned as well.

Split the current is_enabled to 6030 and 4030 specific ones. This
split impacts few macros and variables as well, but sets up the
stage for further fixes to set_mode and get_status in subsequent
patches.

Saquib Herman 776dc923f5 regulator: twl: remap has no meaning for 6030
TWL6030 does not have remap register. The current implementation
causes value of remap to be written to state register, accidentally
causing the regulators which are probed to be switched on as well.
This is wrong as regulators should be controllable based on calls
to enable/disable for TWL regulator framework. Further, the values
initialized make no sense as well. We hence remove this from the
initalizers and also write to remap register only if the TWL
is 4030.

desirable as the SPORT can run at much higher clock frequencies than the
dedicated on-chip SPI peripheral, and it can do full duplex DMA.  It also
opens up the possibility of multiple SPI buses in case someone wants to
dedicate a whole bus to a specific part that does not play well with
others.

If 'max_loop' is 0, there is no restriction on the number of loop devices.
User can create/use the devices as many as minor numbers available. If
'max_part' is 0, it means simply the device doesn't support partitioning.

Also note that 'max_part' can be adjusted to power of 2 minus 1 form if
needed. User should check this value after the module loading if he/she

It is actual for WINE because during a run of WINE program two processes
work on the same netfd - share the same file struct between several VFS

- Fixed potential missed SLI4 device initialization failure conditions.
- Added 100ms delay before driver action following IF_TYPE_2 function reset.
- Reverted patch to UNREG/REG on PLOGI to mapped/unmapped node.
- Add a check for the CVL received flag in the fcf inuse routine to avoid
  unregistering the fcf if Devloss fires before Delay discover timer fires.

Dave Jiang 1ca1e43e55 [SCSI] libsas: Add option for SATA soft reset
This allows a libsas driver to optionally provide a soft reset handler
for libata to drive.  The isci driver allows software to control the
assertion/deassertion of SRST.

Dan Williams 3673f4bf6a [SCSI] libsas: check dev->gone before submitting sata i/o
Head off doomed-to-fail i/o in sas_queuecommand before sending it down
the ata path.

Before:
sd 7:0:0:0: [sdd] Synchronizing SCSI cache
ata8: no sense translation for status: 0x00
ata8: translated ATA stat/err 0x00/00 to SCSI SK/ASC/ASCQ 0xb/00/00
ata8.00: device reported invalid CHS sector 0
ata8: status=0x00 { }
ata8: no sense translation for status: 0x00
ata8: translated ATA stat/err 0x00/00 to SCSI SK/ASC/ASCQ 0xb/00/00
ata8.00: device reported invalid CHS sector 0
ata8: status=0x00 { }
ata8: no sense translation for status: 0x00
ata8: translated ATA stat/err 0x00/00 to SCSI SK/ASC/ASCQ 0xb/00/00
ata8.00: device reported invalid CHS sector 0
ata8: status=0x00 { }
sd 7:0:0:0: [sdd]  Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE
sd 7:0:0:0: [sdd]  Sense Key : Aborted Command [current] [descriptor]
sd 7:0:0:0: [sdd]  Add. Sense: No additional sense information
sd 7:0:0:0: [sdd] Stopping disk

After:
sd 9:0:0:0: [sdd] Synchronizing SCSI cache
sd 9:0:0:0: [sdd]  Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK
sd 9:0:0:0: [sdd] Stopping disk
sd 9:0:0:0: [sdd] START_STOP FAILED
sd 9:0:0:0: [sdd]  Result: hostbyte=DID_BAD_TARGET driverbyte=DRIVER_OK

This is a cosmetic change as sata i/o can still leak to a gone device,
but this addresses the nominal hotplug case when releasing the target.

Dan Williams 90f1e10d08 [SCSI] libsas: fix/amend device gone notification in sas_deform_port()
Commit 56dd2c06 "libsas: Don't issue commands to devices that have been
hot-removed" edited Darrick's original patch to remove setting 'gone' in
the sas_deform_port() path because that prevented scsi sync cache
commands from being issued when the driver was unloaded.  However, this
allows true device gone notifications (as signaled port phy events) to
trigger sync cache commands to devices that are known to be unreachable.

Teach libsas which sas_deform_port() invocations are likely device gone
events.

Axel Lin 80b4037033 spi/tle620x: add missing device_remove_file()
This patch includes below fixes:
1. Add missing device_remove_file for dev_attr_status_show in tle62x0_remove.
2. Fix tle62x0_probe error handling:
   Currently, if the error happens when ptr > 0, gpio_attrs[0] is not
   properly remove.

Joe Perches 3474cb3cc0 gpio: Convert gpio_is_valid to return bool
Make the code a bit more readable.

Instead of casting an int to an unsigned then comparing to
MAX_NR_GPIOS, add a >= 0 test and let the compiler optimizer
do the conversion to unsigned.

The generated code should be the same.

Linus Torvalds f01e1af445 selinux: don't pass in NULL avd to avc_has_perm_noaudit
Right now security_get_user_sids() will pass in a NULL avd pointer to
avc_has_perm_noaudit(), which then forces that function to have a dummy
entry for that case and just generally test it.

Don't do it.  The normal callers all pass a real avd pointer, and this
helper function is incredibly hot.  So don't make avc_has_perm_noaudit()
do conditional stuff that isn't needed for the common case.

This also avoids some duplicated stack space.
