ALSA: replace CONFIG_PROC_FS with CONFIG_SND_PROC_FS

2015-05-27T19:25:19+00:00

We may disable proc fs only for sound part, to reduce ALSA
memory footprint. So add CONFIG_SND_PROC_FS and replace the
old CONFIG_PROC_FSs in alsa code.

With sound proc fs disabled, we can save about 9KB memory
size on X86_64 platform.

ALSA: core: Drop superfluous error/debug messages after malloc failures

2015-03-10T14:42:14+00:00

The kernel memory allocators already report the errors when the
requested allocation fails, thus we don't need to warn it again in
each caller side.

ALSA: snd_pcm_oss_period_size: Use round{up,down}_pow_of_two()

2014-12-30T15:41:55+00:00

Instead of opencoding them use the standard roundup_pow_of_two() and
rounddown_pow_of_two() helper functions. This gets rids one of the few users
of the custom ld2() function and also makes it a bit more obvious what the
code does.

ALSA: oss: Use standard printk helpers

2014-02-14T07:14:17+00:00

Use dev_err() & co as much as possible.  If not available (no device
assigned at the calling point), use pr_xxx() helpers instead.

ALSA: Drop unused name argument in snd_register_oss_device()

2014-02-12T09:58:19+00:00

The last argument, name, of snd_oss_register_device() is nowhere
referred in the function in the current code.  Let's drop it.

ALSA: Fix card refcount unbalance

2012-11-08T13:36:18+00:00

There are uncovered cases whether the card refcount introduced by the
commit a0830dbd isn't properly increased or decreased:
- OSS PCM and mixer success paths
- When lookup function gets NULL

This patch fixes these places.

ALSA: Avoid endless sleep after disconnect

2012-10-30T10:07:15+00:00

When disconnect callback is called, each component should wake up
sleepers and check card->shutdown flag for avoiding the endless sleep
blocking the proper resource release.

ALSA: Add a reference counter to card instance

2012-10-30T10:07:10+00:00

For more strict protection for wild disconnections, a refcount is
introduced to the card instance, and let it up/down when an object is
referred via snd_lookup_*() in the open ops.

The free-after-last-close check is also changed to check this refcount
instead of the empty list, too.
