ALSA: ak411x: Fix stall in work callback

2015-03-06T00:39:17+00:00

commit 4161b4505f1690358ac0a9ee59845a7887336b21 upstream.

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.

[bwh: Backported to 3.2: snd_ak411{3,4}_reinit were previously using
 flush_delayed_work_sync() rather than flush_delayed_work()]

sound: Add module.h to the previously silent sound users

2011-10-31T23:31:21+00:00

Lots of sound drivers were getting module.h via the implicit presence
of it in  but we are going to clean that up.  So
fix up those users now.

[media] tea575x: convert to control framework

2011-07-27T20:52:20+00:00

Convert tea575x-tuner to use the new V4L2 control framework. Also add
ext_init() callback that can be used by a card driver for additional
initialization right before registering the video device (for SF16-FMR2).

Also embed struct video_device to struct snd_tea575x to simplify the code.

ALSA: tea575x: unify read/write functions

2011-05-10T07:29:42+00:00

Implement generic read/write functions to access TEA575x tuners. They're now
implemented 4 times (once in es1968 and 3 times in fm801).
This also allows mute to work on all cards.
Also improve tuner detection/initialization.
