ALSA: hda - restore the gpio led after resume

On some HP laptops, the mute led is controlled by codec gpio.

When some machine resume from s3/s4, the codec gpio data will be
cleared to 0 by BIOS:
Before suspend:
  IO[3]: enable=1, dir=1, wake=0, sticky=0, data=1, unsol=0
After resume:
  IO[3]: enable=1, dir=1, wake=0, sticky=0, data=0, unsol=0

To skip the AFG node to enter D3 can't fix this problem.

A workaround is to restore the gpio data when the system resume
back from s3/s4. It is safe even on the machines without this
problem.

ALSA: hda/realtek - Avoid setting wrong COEF on ALC269 & co

ALC269 & co have many vendor-specific setups with COEF verbs.
However, some verbs seem specific to some codec versions and they
result in the codec stalling.  Typically, such a case can be avoided
by checking the return value from reading a COEF.  If the return value
is -1, it implies that the COEF is invalid, thus it shouldn't be
written.

This patch adds the invalid COEF checks in appropriate places
accessing ALC269 and its variants.  The patch actually fixes the
resume problem on Acer AO725 laptop.

ASoC: Intel: Restore Baytrail ADSP streams only when ADSP was in reset

There is no need to restore and restart PCM streams in case ADSP didn't
reach reset and power off state during system suspend/resume cycle. In that
case stream is still active but paused and firmware doesn't allow allocating
a new stream before paused stream is freed.

ADSP remains active in case suspend sequence didn't go to suspend_late
stage. This can happen when either suspend sequence is aborted by a wakeup
or by letting only devices suspend by "echo devices >/sys/power/pm_test".

Currently stream restoring fails in these suspend cases. Fix this by adding
a flag that indicates is complete stream reinitialization needed or is it
enough to resume paused stream. Flag is set when we know that ADSP reached
suspend_late.

Initial fix to this issue came from Fang Yang. I modified it a little and
forward ported it to top of two other suspend/resume patches from me.

CMI8888 codec chip has a boost amp (only) on the headphone pin, and
this confuses the generic parser, which tends to pick up the most
outside amp.  This results in the wrong volume setup, as the driver
complains like:
  hda_codec: Mismatching dB step for vmaster slave (-100!=1000)

For avoiding this problem, rule out the amp on NID 0x10 and create
"Headphone Amp" volume control manually instead.

Note that this patch still doesn't fix all problems yet.  The sound
output from the line out seems still too low.  It will be fixed in
another patch (hopefully).

ALSA: hda - Fix probing and stuttering on CMI8888 HD-audio controller

ASUS Phoebus with CMI8888 HD-audio chip (PCI id 13f6:5011) doesn't
work with HD-audio driver as is because of some weird nature.  For
making DMA properly working, we need to disable MSI.  The position
report buffer doesn't work, thus we need to force reading LPIB
instead.  And yet, the codec CORB/RIRB communication gives errors
unless we disable the snooping (caching).

In this patch, all these workarounds are added as a quirk for the

it'll be provided in the succeeding patch.

this.

Otherwise it's been a fairly standard release for development, including
more componentisation work from Lars-Peter and a good selection of both
CODEC and CPU drivers.

 - Support for multiple CODECs attached to a single DAI, enabling
   systems with for example multiple DAC/speaker drivers on a single
   link, contributed by Benoit Cousson based on work from Misael Lopez
   Cruz.
 - Support for byte controls larger than 256 bytes based on the use of
   TLVs contributed by Omair Mohammed Abdullah.
 - More componentisation work from Lars-Peter Clausen.
 - The remainder of the conversions of CODEC drivers to params_width()
 - Drivers for Cirrus Logic CS4265, Freescale i.MX ASRC blocks, Realtek
   RT286 and RT5670, Rockchip RK3xxx I2S controllers and Texas Instruments

 - Lots of updates and fixes, especially to the DaVinci, Intel,

ASoC: fsl_sarc_dma: Check pair before using it

The patch 3117bb3109dc: "ASoC: fsl_asrc: Add ASRC ASoC CPU DAI and
platform drivers" from Jul 29, 2014, leads to the following Smatch
complaint:

warn: variable dereferenced before check 'pair' (see line 302)

302          struct fsl_asrc *asrc_priv = pair->asrc_priv;

Greg Thelen [Thu, 31 Jul 2014 16:07:19 +0000 (09:07 -0700)]
dm bufio: fully initialize shrinker

1d3d4437eae1 ("vmscan: per-node deferred work") added a flags field to
struct shrinker assuming that all shrinkers were zero filled.  The dm
bufio shrinker is not zero filled, which leaves arbitrary kmalloc() data
in flags.  So far the only defined flags bit is SHRINKER_NUMA_AWARE.
But there are proposed patches which add other bits to shrinker.flags
(e.g. memcg awareness).

Rather than simply initializing the shrinker, this patch uses kzalloc()
when allocating the dm_bufio_client to ensure that the embedded shrinker
and any other similar structures are zeroed.

This fixes theoretical over aggressive shrinking of dm bufio objects.
If the uninitialized dm_bufio_client.shrinker.flags contains
SHRINKER_NUMA_AWARE then shrink_slab() would call the dm shrinker for
each numa node rather than just once.  This has been broken since 3.12.

10 years agotimer: Fix lock inversion between hrtimer_bases.lock and scheduler locks

timer: Fix lock inversion between hrtimer_bases.lock and scheduler locks

clockevents_increase_min_delta() calls printk() from under
hrtimer_bases.lock. That causes lock inversion on scheduler locks because
printk() can call into the scheduler. Lockdep puts it as:
