ALSA: ak411x: Fix race of reinit() calls

2015-01-28T21:30:18+00:00

Protect the call with a mutex, as this may be called in parallel
(either from the PCM rate change and the clock change).

ALSA: ak411x: Add PM helper functions

2015-01-28T21:30:12+00:00

Define snd_ak4114_suspend() and snd_ak4114_resume() functions to
handle PM properly, stopping and restarting the work at PM.
Currently only ice1712/juli.c deals with the PM and ak4114, so fix the
calls there appropriately.

The same PM functions are defined in ak4113.c, too, although they
aren't currently called yet (ice1712/quartet.c may be enhanced to
support PM later).

ALSA: ak411x: Fix stall in work callback

2015-01-28T21:29:20+00:00

When ak4114 work calls its callback and the callback invokes
ak4114_reinit(), it stalls due to flush_delayed_work().  For avoiding
this, control the reentrance by introducing a refcount.  Also
flush_delayed_work() is replaced with cancel_delayed_work_sync().

The exactly same bug is present in ak4113.c and fixed as well.

ALSA: ak4114: Fix wrong register array size

2013-10-29T15:42:36+00:00

The size of the register cache array is actually 6 instead of 7,
as it caches up to AK4114_REG_INT1_MASK.  This resulted in unexpected
access out of array range, although most of them aren't so serious
(just reading one more byte on the stack at snd_ak4114_create()).

Also, the check of cache size was wrongly done by checking with
sizeof() instead of ARRAY_SIZE().  Fixed this together.

(And yes, hardcoded numbers are bad, but I keep the coding style as is
 for making it clear what this patch actually does.)

Spotted by coverity among several CIDs, e.g. 711621.

ALSA: ak4114 - fix errors in output selector bits

2009-09-21T13:44:39+00:00

  identical with AK4114_OPS00-02
* Since no cards actually use this feature, the bug was not identified earlier
