      ALSA: ctxfi - Fix deadlock with xfi-timer · 8dca4197
      Takashi Iwai authored 
      The PCM x-fi native update routine can cause deadlocks when the
trigger(START) is called while the stream is running.

This patch fixes the deadlock by just postponing the pcm period update
to the next possible wake-up.  Also it adds the flip of ti->running
flag (just to be sure as now).

      ALSA: intel8x0 - Fix PCM position craziness · f708eb1d
      Takashi Iwai authored 
      The PCM pointer callback sometimes returns invalid positions and this
screws up the hw_ptr updater in PCM core.  Especially since now the
jiffies check is optional with xrun_debug, the invalid position is
handled as is, and causes serious sound skips, etc.

This patch simplifies the position-fix strategy in intel8x0 to be more
robust:
- just falls back to the last position if bogus position is detected
- another sanity check for the backward move of the position due to
  a race of register update and the base-index update

This patch is applicable also for 2.6.30.

      ASoC: Revert duplicated code in SSM2602 driver · 5ba73683
      Mark Brown authored 
      The Blackfin submission was done as a patch against a different tree
and contained a duplicate hunk which will cause us to loose track of the
substream pointers when shutting down.  Remove one of the duplicated
hunks.

      ALSA: ctxfi - Replace atc lock to mutex · 635c265f
      Takashi Iwai authored 
      The spinlock in atc can cause a sleep in lock:

Since the lock path is no critical path, it can be gracefully
replaced with a mutex.
