      ASoC: Clean up error handling in MPC5200 DMA setup · 33d7f778

      Error handling code following a kzalloc should free the allocated data.

      ASoC: au1x: PSC-AC97 bugfixes · cdc65fbe
      由 Manuel Lauss 提交于 
      This patch fixes the following bugs:

- only reprogram bitdepth if it has changed since last call to hw_params.
- add locking inside ac97_read/write functions:
  When reprogramming sample depth, the ac97 unit has to be disabled,
  which should not be done in the middle of codec register accesses.

- retry timed-out codec register accesses.

- wait for status bits to set/clear when starting/stopping various
  functional blocks; very important after reenabling AC97 unit else
  sound may be distorted (e.g. high-pitch noise in 1kHz sine wave).

- clear fifos before/after starting/stopping RX/TX.

- longer timeouts waiting for PSC/AC97 ready after cold reset
  with certain codecs this can take ridiculous amounts of time.

Run-tested on various Au1200 platforms with various codecs.

      ALSA: dummy - Increase MAX_PCM_SUBSTREAMS to 128 · b888d1ce
      由 Takashi Iwai 提交于 
      Increase the limit of PCM substreams to 128.  The default value is
unchanged; only the max accept value is increased.

      ALSA: Remove struct snd_monitor_file from public sound/core.h · 82a783f4
      由 Takashi Iwai 提交于 
      The struct snd_monitor_file is used locally only in sound/core/init.c,
thus it should be moved there from the public sound/core.h.

      sound: oxygen: work around MCE when changing volume · f1bc07af
      由 Clemens Ladisch 提交于 
      When the volume is changed continuously (e.g., when the user drags a
volume slider with the mouse), the driver does lots of I2C writes.
Apparently, the sound chip can get confused when we poll the I2C status
register too much, and fails to complete a read from it.  On the PCI-E
models, the PCI-E/PCI bridge gets upset by this and generates a machine
check exception.

To avoid this, this patch replaces the polling with an unconditional
wait that is guaranteed to be long enough.

      ALSA: dummy - Fake buffer allocations · a68c4d11
      由 Takashi Iwai 提交于 
      Instead of allocating the real buffers, use a fake buffer and ignore
read/write in the dummy driver so that we can save the resources.
For mmap, a single page (unique to the direction, though) is reused
to all buffers.

When the app requires to read/write the real buffers, pass fake_buffer=0
module option at loading time.  This will get back to the old behavior.
