d2b9b96c51 ALSA: ctxfi - Fix supported PCM formats 
The device seems supporting only U8, S16, S24_3LE, S32.  Other linear
formats result in bad outputs.

Also, added the support for 32bit float format, which wasn't listed
in the original code.

8372d4980f ALSA: ctxfi - Fix PCM device naming 
PCM names for surround streams should be also fixed as well as the mixer
element names.  Also, a bit clean up for PCM name setup.

822fa19b5c ALSA: ALSA: ctxfi - Release PCM resources at each prepare call 
The prepare callback can be called multiple times, thus it needs to
release and acquire the resource again by itself at the second or later
call.

Simply add pcm_release_resources() at the beginning of each prepare
callback in ctatc.c.

Replace a spinlock with a mutex protecting the vm block list at
mmap / munmap calls, which caused Oops like below:
