2008-10-20ALSA: pcsp - Fix locking messes in snd-pcspTakashi Iwai
snd-pcsp driver takes chip->substream_lock together with PCM substream lock. These are even mixed up with hrtimer's lock, resulting in messy lock depencies. Right now, snd-pcsp driver resolves the deadlock by using HRTIMER_CB_SOFTIRQ. However, this isn't nice for a really fast path like bit-flipping. This patch introduces a tasklet for PCM period handling so that the hrtimer callback can be handled fast. This also reduce the use of chip->substream_lock to avoid deadlocks. It's still used in pointer callback, but even this could be removed with a proper barrier. Another good solution is to introduce async trigger callback. But, this will involve with a major rewrite of the PCM core code, so I take first this easy fix. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2008-08-15sound: Fix esoteric double free in the dummy sound driver.Daniel THOMPSON
The dummy driver uses runtime->private_free but still frees its pcm structures on error paths. This is esoteric because the error paths in question are unreachable.

2008-07-10Fix a const pointer usage warning in the Digigram VX soundcard driverDavid Howells
Fix a const pointer usage warning in the Digigram VX soundcard driver. A const pointer is being passed to copy_from_user() to load the firmware into. This is okay in this case because the function has allocated the firmware struct itself, but the const qualifier will be part of the firmware struct - so the patch casts the const away.
