2015-01-28ALSA: ak411x: Fix race of reinit() callsTakashi Iwai
Protect the call with a mutex, as this may be called in parallel (either from the PCM rate change and the clock change). Acked-by: Jaroslav Kysela <perex@perex.cz> Tested-by: Pavel Hofman <pavel.hofman@ivitera.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-01-28ALSA: ak411x: Add PM helper functionsTakashi Iwai
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).

2015-01-28ALSA: ak411x: Fix stall in work callbackTakashi Iwai
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.

2013-10-29ALSA: ak4114: Fix wrong register array sizeTakashi Iwai
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.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
