Subject: ALSA: ctxfi - Fix supported PCM formats
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d2b9b96c516d4d61663d92ab4ad4f15ca0134ef2;p=linux-beck.git

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.
