Suppress warning of unused-variables by adding a BUG()+return for invalid audio-formats.

Cc: Rob Clark robdclark@gmail.com Signed-off-by: David Herrmann dh.herrmann@gmail.com --- Hey Rob

No idea whether it's correct. But all I know is when we hit the default: path, several variables will be unset. To avoid gcc warn about it, I added the BUG(). If we should just silently return, feel free to adjust the patch to your needs.

Cheers David
