This function is a bit unusual because it accepts negative values as
"conn_len".  It's theoretically possible for both "cache_len" and
"conn_len" to be -ENOSPC and in that case we would oops trying to run
memcmp() on the uninitialized "list" pointer.

The commit [a551d914: ALSA: hda - Use regmap for command verb
caches, too] introduced a regression due to a typo in the conversion;
the IEC958 status bits of slave digital devices aren't updated
correctly.  This patch corrects it.

Some HD-A codecs may add their own vendor 'set' verb to the regmap, thru func
snd_hdac_add_vendor_verb(). This patch sets the GET bit (bit 11)  when adding
the verb so that its peer vendor 'get' verb is actually added. This can avoid
I/O error when writing the 'set' verb thru remap, since HD-A regmap internally
looks up a writable vendor verb with GET bit set at first.

ASoC: Updates for v4.1

More updates for v4.1, pretty much all drivers:

 - Lots of cleanups from Lars, mainly moving things from the CODEC level
   to the card level.
 - Continuing improvements to rcar from Morimoto-san, pcm512x from
   Howard and Peter, the Intel platforms from Vinod, Jie, Jin and Han,
   and to rt5670 from Bard.
 - Support for some non-DSP Qualcomm platforms, Google's Storm
   platform, Maxmim MAX98925 CODECs and the Ingenic JZ4780 SoC.

The Lenovo Thinkpad T450 requires the ALC292_FIXUP_TPT440_DOCK as well in
order to get working sound output on the docking stations headphone jack.

Patch tested on a Thinkpad T450 (20BVCTO1WW) using kernel 4.0-rc7 in
conjunction with a ThinkPad Ultradock.

Although some races in runtime PM refcount was fixed by the commit
[664c7155: ALSA: hda - Work around races of power up/down with
runtime PM], there is still a race in the following case:

CPU0:                   CPU1 :
runtime suspend:
  codec->in_pm = 1
                        snd_hdac_power_up_pm():
                          pm_runtime_get_sync() skipped
suspend finished:
  codec->in_pm = 0
                        snd_hdac_power_down_pm():
                          pm_runtime_put_*() is called!

For avoiding this situation, increment in_pm flag atomically when it's
non-zero, and decrement accordingly, to ensure that in_pm is set
consistently for the whole concurrent operations.

Also, since atomic_inc_not_zero() and atomic_dec_if_positive() are
lengthy inline functions, move snd_hdac_power_up_pm() and _down_pm()
to sound/hda/hdac_device.c as no inline functions.

The type field of HD-audio codec object should be exposed to
user-space so that it can identify which driver type to bind (legacy /
asoc).
Signed-off-by: NTakashi Iwai <tiwai@suse.de>

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.

ASoC: Last minute fix for v4.0

This patch backs out a change that came in during the merge window which
selects a configuration for GPIO4 on pcm512x CODECs that may not be
suitable for all systems using the device.  Changes for v4.1 will make
this properly configurable but for now it's safest to revert to the
v3.19 behaviour and leave the pin configuration alone.

Sorry for sending this direct at the last minute but due to the GPIO
misuse it'd be really good to get it in the release and I'd not realised
it hadn't been sent yet - between some travel, a job change and other
non-urgent fixes coming in I'd lost track of the urgency.  It's been in
-next for several weeks now, is isolated to the driver and fairly clear
to inspection.

sound/soc/intel/haswell/sst-haswell-ipc.c:646:28-29: WARNING: Use ARRAY_SIZE

 Use ARRAY_SIZE instead of dividing sizeof array with sizeof an element

Semantic patch information:
 This makes an effort to find cases where ARRAY_SIZE can be used such as
 where there is a division of sizeof the array by the sizeof its first
 element or by any indexed element or the element type. It replaces the
 division of the two sizeofs by ARRAY_SIZE.
