 biggest one is the fix from Tony for some confusion with the device
 property API which was causing issues with the of-graph card.  This is
 fixed with some changes in the graph API itself as it seemed very likely

5051735221 ALSA: pcxhr: fix string overflow warnings
With gcc-7, we get a warning about a possible string overflow:

sound/pci/pcxhr/pcxhr.c: In function 'pcxhr_probe':
sound/pci/pcxhr/pcxhr.c:1647:28: error: ' [PCM #' directive writing 7 bytes into a region of size between 1 and 32 [-Werror=format-overflow=]

The shortname can simply be removed, and the longname can
be changed into a shorter "name" string that is used in three
places. Making it a little shorter (40 bytes) avoids the risk of
overflowing completely, but I also use snprintf() here for
extra clarity.

7ad210ace5 ALSA: rme9652: fix format overflow warnings
gcc-7 warns about a possible sprintf format string overflow with a
temporary buffer that is used to print from another buffer of the same
size:

sound/pci/rme9652/hdspm.c: In function 'snd_hdspm_create_alsa_devices':
sound/pci/rme9652/hdspm.c:2123:17: error: ' MIDIoverMADI' directive writing 13 bytes into a region of size between 1 and 32 [-Werror=format-overflow=]

This extends the temporary buffer to twice the size, and changes
the code to use the safer snprintf() across the entire file.
The longer buffer is still necessary to avoid a format-truncation
warning.

Somehow it prevents FM801-AU to work properly. Thus, partially revert

920f2ecdf6 sound updates for 4.13-rc1
This development cycle resulted in a fair amount of changes in both
 core and driver sides.  The most significant change in ALSA core is
 about PCM.  Also the support of of-graph card and the new DAPM widget
 for DSP are noteworthy changes in ASoC core.  And there're lots of
 small changes splat over the tree, as you can see in diffstat.
 
 Below are a few highlights:
 
 ALSA core:
 - Removal of set_fs() hackery from PCM core stuff, and the code
   reorganization / optimization thereafter
 - Improved support of PCM ack ops, and a new ABI for improved
   control/status mmap handling
 - Lots of constifications in various codes
 
 ASoC core:
 - The support of of-graph card, which may work as a better generic
   device for a replacement of simple-card
 - New widget types intended mainly for use with DSPs
 
 ASoC drivers:
 - New drivers for Allwinner V3s SoCs
 - Ensonic ES8316 codec support
 - More Intel SKL and KBL works
 - More device support for Intel SST Atom (mostly for cheap tablets and
   2-in-1 devices)
 - Support for Rockchip PDM controllers
 - Support for STM32 I2S and S/PDIF controllers
 - Support for ZTE AUD96P22 codecs
 
 HD-audio:
 - Support of new Realtek codecs (ALC215/ALC285/ALC289), more quirks
   for HP and Dell machines
 - A few more fixes for i915 component binding
 
 Note that of-graph change may bring the conflicts with a later pull
 request of devicetree, as currently found in linux-next.

Merge tag 'sound-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "This development cycle resulted in a fair amount of changes in both
  core and driver sides. The most significant change in ALSA core is
  about PCM. Also the support of of-graph card and the new DAPM widget
  for DSP are noteworthy changes in ASoC core. And there're lots of
  small changes splat over the tree, as you can see in diffstat.

  Below are a few highlights:

  ALSA core:
   - Removal of set_fs() hackery from PCM core stuff, and the code
     reorganization / optimization thereafter
   - Improved support of PCM ack ops, and a new ABI for improved
     control/status mmap handling
   - Lots of constifications in various codes

  ASoC core:
   - The support of of-graph card, which may work as a better generic
     device for a replacement of simple-card
   - New widget types intended mainly for use with DSPs

  ASoC drivers:
   - New drivers for Allwinner V3s SoCs
   - Ensonic ES8316 codec support
   - More Intel SKL and KBL works
   - More device support for Intel SST Atom (mostly for cheap tablets
     and 2-in-1 devices)
   - Support for Rockchip PDM controllers
   - Support for STM32 I2S and S/PDIF controllers
   - Support for ZTE AUD96P22 codecs

  HD-audio:
   - Support of new Realtek codecs (ALC215/ALC285/ALC289), more quirks
     for HP and Dell machines
   - A few more fixes for i915 component binding"

dba9b7b6ca ALSA: hda - Fix doubly initialization of i915 component
In the commit fcc88d91cd ("ALSA: hda - Bind with i915 component
before codec binding"), the binding with i915 audio component is moved
to be performed always at probing the controller.  This fixed the
potential problems on IVB, but now it brought another issue on HSW and
BDW.  These two platforms give two individual HD-audio controllers,
one for the analog codec on PCH and another for HDMI over gfx.  Since
I decided to take a lazy path to check only AZX_DRIVER_PCH type in the
commit above, now both controllers try to bind with i915, and you see
a kernel WARNING.

This patch tries to address it again properly.  Now a new DCAPS bit,
AZX_DCAPS_I915_COMPONENT, is introduced for indicating the binding
with i915 component in addition to the existing I915_POWERWELL bit
flag.  Each PCI entry has to give this new flag if it requires the
binding with i915 component.  For HSW/BDW PCH (i.e. the ones defined
by AZX_DCAPS_INTEL_PCH) doesn't contain AZX_DCAPS_I915_COMPONENT bit
while others have it.

While we're at it, add parentheses around the bit flag check for
avoiding possible compiler warnings, too.

The bug was spotted by Intel CI tests.

fcc88d91cd ALSA: hda - Bind with i915 component before codec binding
We used a on-demand i915 component binding for IvyBridge and
SandyBridge HDMI codecs, but it has a potential problem of the nested
module loading.  For avoiding that situation, assure the i915 binding
happening at the controller driver level for PCH controller devices,
where the initialization is performed in a detached work, instead of
calling from the codec driver probe.

d94815f917 ALSA: hda - Fix endless loop of codec configure
azx_codec_configure() loops over the codecs found on the given
controller via a linked list.  The code used to work in the past, but
in the current version, this may lead to an endless loop when a codec
binding returns an error.

The culprit is that the snd_hda_codec_configure() unregisters the
device upon error, and this eventually deletes the given codec object
from the bus.  Since the list is initialized via list_del_init(), the
next object points to the same device itself.  This behavior change
was introduced at splitting the HD-audio code code, and forgotten to
adapt it here.

For fixing this bug, just use a *_safe() version of list iteration.

a8f20fd25b ALSA: hda - set input_path bitmap to zero after moving it to new place
Recently we met a problem, the codec has valid adcs and input pins,
and they can form valid input paths, but the driver does not build
valid controls for them like "Mic boost", "Capture Volume" and
"Capture Switch".

Through debugging, I found the driver needs to shrink the invalid
adcs and input paths for this machine, so it will move the whole
column bitmap value to the previous column, after moving it, the
driver forgets to set the original column bitmap value to zero, as a
result, the driver will invalidate the path whose index value is the
original colume bitmap value. After executing this function, all
valid input paths are invalidated by a mistake, there are no any
valid input paths, so the driver won't build controls for them.

Rename:

'wait_queue_t' was always a slight misnomer: its name implies that it's a "queue",
but in reality it's a queue *entry*. The 'real' queue is the wait queue head,
which had to carry the name.

Start sorting this out by renaming it to 'wait_queue_entry_t'.

This also allows the real structure name 'struct __wait_queue' to
lose its double underscore and become 'struct wait_queue_entry',
which is the more canonical nomenclature for such data types.
