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.

... instead of SNDRV_DEV_LOWLEVEL.
No functional change at this point.

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: Use strlcpy() instead of strncpy()

2013-10-29T14:26:12+00:00

We tend to make stupid mistakes with strncpy().  Let's take a safer
one, strlcpy().

[media] tea575x-tuner: move HW init to a separate function

2013-07-26T16:32:15+00:00

Move HW initialization to separate function to allow using the code without
the v4l parts. This is needed for use in the bttv driver.
