driver core fixes for 4.9-rc5

Here are two driver core fixes for 4.9-rc5.

The first resolves an issue with some drivers not liking to be unbound
and bound again (if CONFIG_DEBUG_TEST_DRIVER_REMOVE is enabled), which
solves some reported problems with graphics and storage drivers.  The
other resolves a smatch error with the 4.9-rc1 driver core changes
around this feature.

Both have been in linux-next with no reported issues.

Power management fixes for v4.9-rc5

 - Prevent the PM core from attempting to suspend parent devices
   if any of their children, whose suspend callbacks were invoked
   asynchronously, have failed to suspend during the "late" and
   "noirq" phases of system-wide suspend of devices (Brian Norris).

 - Prevent the boot-time system suspend test code from leaking a
   reference to the RTC device used by it (Johan Hovold).

 - Fix cpupower to use the return value of one of its library
   functions correctly and restore the correct behavior of it
   when used for setting cpufreq tunables broken during the 4.7
   development cycle (Laura Abbott).

ACPI fix for v4.9-rc5

Fix a recent regression in the 8250_dw serial driver introduced by
adding a quirk for the APM X-Gene SoC to it which uncovered an issue
related to the handling of built-in device properties in the core
ACPI device enumeration code (Heikki Krogerus).

amd, radeon, i915, imx, msm and udl fixes

This is the 4.8.7 stable release

This is the 4.4.31 stable release

This is the 3.12.67 stable release

sound fixes for 4.9-rc5

this became a largish pull-request, as we've got a bunch of pending
ASoC fixes at this time.  One noticeable change is the removal of
error directive in uapi/sound/asoc.h.  We found that the API has
been already used on Chromebooks, so we need to support it even now.

A slight big LOC is found in Qualcomm lpass driver, but the rest are
all small and easy fixes for ASoC drivers (sti, sun4i, Realtek codecs,
Intel, tas571x, etc) in addition to the patches to harden the ALSA
core proc file accesses.

IOMMU-Fixes for Linux v4.9-rc4

Two places need fixing:

	* Four patches from Robin Murphy fix several issues with the
	  recently merged generic DT-bindings support for arm-smmu
	  drivers

	* A fix for a dead-lock issue in the VT-d driver, which shows up
	  on iommu hotplug

- vlv mappable scanout fix
- speed up probing in resume (Lyude)
- dp audio workarounds for gen9 (Dhinakaran)
- more conversion to using dev_priv internally (Ville)
- more gen9+ wm fixes and cleanups (Maarten)
- shrinker cleanup&fixes (Chris)
- reorg plane init code (Ville)
- implement support for multiple timelines (prep work for scheduler)
  from Chris and all
- untangle dev->struct_mutex locking as prep for multiple timelines
  (Chris)
- refactor bxt phy code and collect it all in intel_dpio_phy.c (Ander)
- another gvt with bugfixes all over from Zhenyu
- piles of lspcon fixes from Imre
- 90/270 rotation fixes (Ville)
- guc log buffer support (Akash+Sagar)
- fbc fixes from Paulo
- untangle rpm vs. tiling-fences/mmaps (Chris)
- fix atomic commit to wait on the right fences (Daniel Stone)

Second set of IIO fixes for the 4.9 cycle.

Interestingly scale related fixes for accelerometers at both ends of
the range.  Obviously more varied devices turning up than we've seen before!

* ad5933
  - fix an uninitialized value in a return case that is winding up GCC.
* hid sensors
  - missing pm function prevents hid rotations sensors from working on newer
  ISH hubs (works by luck on older ones)
  - increase of scale precision needed to fix a case where on a yoga 260
  the reported scale is 0 (presumably a high precision but very low g sensor).
* st_sensors
  - fix an issue seen with the hs3lis331dl where the range is much greater
  than previous devices (100's of g) and hence the per bit scale is greater
  than 1.

Second round of new device support, cleanups and fixes for IIO in the 4.10 cycle

This includes two branch merges for elements that may also go via MFD.

New device support
* cros_ec
  - new driver to support these Chrome OS contiguous sensors which are behind
    the Chrome OS embedded controller.  Requires a few minor MFD and chrome
    platform changes.  One follow up fix deals with some dependency issues in
    Kconfig.
* mpu-3050
  - new driver and device tree bindings for this venerable device.
* st_accel
  - support for the lng2dm an

Driver features
* ad7192
  - Add DVdd regulator handling
* ad9832
  - Add DVDD regulator handling
* at91
  - Suspend and resume support
* si7020
  - Device tree bindings
* ti-am335x
  - DMA support - uses dma to accelerate short bursts of read back rather
  than full blown DMA buffer support.  Greatly improved performance.
  Includes an MFD addition to give access to the address needed for DMA.
* tsl2583
  - Device tree bindings

Cleanups and minor fixes
* ad7192
  - Fix regulator naming to match datasheet
  - Handle regulator errors correctly (so as to not break deferred probing)
  - Rename reg variable to reflect which regulator it is
* ad5933
  - Fix regulator naming to match datasheet
  - Handle regulator errors correctly (so as to not break deferred probing)
* ad7746
  - Fix a missing return value (fallout from previous patch set)
* ad7780
  - Fix regulator naming to match datasheet
  - Handle regulator errors correctly (so as to not break deferred probing)
* ad9832
  - Fix regulator naming to match datasheet
  - Handle regulator errors correctly (so as to not break deferred probing)
  - Rename reg regulator to reflect which one it is
* ad9834
  - Fix regulator naming to match datasheet
  - Handle regulator errors correctly (so as to not break deferred probing)
* hts221
  - Remove a duplicated include
* maxim thermocouple
  - Handle a wrong storage side in read function.  Prevent any problems that
  might be introduced by additions to this driver in future.
* tsl2583 - big set from Brian Masney to drive this towards a staging
  graduation.
  - Convert to iio_chan_spec and read_raw / write_raw (in a couple of steps)
  - Improved error handling in various functions
  - Drop redundant power_state custom sysfs attribute.
  - Use IIO_*_ATTR* macros for remaining attributes.
  - Return an error code to userspace on invalid parameters being writen to
    sysfs files.
  - Add locking to various attribute accesses to remove possible races.
  - Add defines for various magic numbers.
  - Use smbus_read_byte_data instead of a write_byte followed by read_byte.
  - Query only relevant registers in probe.
  - Tidy up ordering of code comments.
  - Remove a pointless power off sequence in taos_chip_on.
  - Don't bother shutting down the chip when updating the lux table.
  The table is held entirely in the driver and doesn't effect the chip at all.
  - Drop a redundant i2c call in taos_als_calibrate where the same register
  is read twice in a row.
