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: ak4117: Do not free priv until timer handler hasn't actually stopped using it

2014-02-14T13:41:52+00:00

Function del_timer() does not guarantee that timer was really deleted.
If the timer handler is beeing executed at the moment, the function
does nothing. So, it's possible to use already freed memory in the handler:

This was found using grep and compile-tested only.
