      ALSA: cs46xx: constify snd_pcm_ops structures · a6f9dec2
      由 Bhumika Goyal 提交于 
      Declare snd_pcm_ops structures as const as they are either stored in the
ops field of a snd_pcm_substream structure or passed as an argument to
the function snd_pcm_set_ops. The function argument and the ops field
are of type const, so snd_pcm_ops structures having this property
can be made const too.

      ALSA: hda - Make single_cmd option to stop the fallback mechanism · 41438f13
      由 Takashi Iwai 提交于 
      HD-audio driver has a mechanism to fall back to the single cmd mode as
a last resort if the CORB/RIRB communication goes wrong even after
switching to the polling mode.  The switching has worked in the past
well, but Enrico Mioso reported that his system crashes when this
happens.

Although the actual cause of the crash isn't still fully analyzed yet,
it'd be in anyway good to provide an option to turn off the fallback
mode.  Now this patch extends the behavior of the existing single_cmd
option for that.  Namely,

- The option is changed from bool to bint.
- As default, it is the mode allowing the fallback to single cmd.
- Once when either true/false value is given to the option, the driver
  explicitly turns on/off the single cmd mode, but without the
  fallback.

That is, if you want to disable the fallback, just pass single_cmd=0
option.  Passing single_cmd=1 will keep working like before.

      ALSA: hda - Fix up GPIO for ASUS ROG Ranger · 85bcf96c
      由 Takashi Iwai 提交于 
      ASUS ROG Ranger VIII with ALC1150 codec requires the extra GPIO pin to
up for the front panel.  Just use the existing fixup for setting up
the GPIO pins.

      ALSA: hda - Fix deadlock of controller device lock at unbinding · ab949d51
      由 Takashi Iwai 提交于 
      Imre Deak reported a deadlock of HD-audio driver at unbinding while
it's still in probing.  Since we probe the codecs asynchronously in a
work, the codec driver probe may still be kicked off while the
controller itself is being unbound.  And, azx_remove() tries to
process all pending tasks via cancel_work_sync() for fixing the other
races (see commit [0b8c8219: ALSA: hda - Cancel probe work instead
of flush at remove]), now we may meet a bizarre deadlock:

Unbind snd_hda_intel via sysfs:
  device_release_driver() ->
    device_lock(snd_hda_intel) ->
      azx_remove() ->
        cancel_work_sync(azx_probe_work)

azx_probe_work():
  codec driver probe() ->
     __driver_attach() ->
       device_lock(snd_hda_intel)

This deadlock is caused by the fact that both device_release_driver()
and driver_probe_device() take both the device and its parent locks at
the same time.  The codec device sets the controller device as its
parent, and this lock is taken before the probe() callback is called,
while the controller remove() callback gets called also with the same
lock.

In this patch, as an ugly workaround, we unlock the controller device
temporarily during cancel_work_sync() call.  The race against another
bind call should be still suppressed by the parent's device lock.
