[ Upstream commit 55ff2d1ea5487fe131cce399baf4503dcf5cc8e1 ]
The PCM format type in snd_pcm_format_t can't be treated as integer
implicitly since it's with __bitwise. We have already a helper
function to get the bit index of the given type, and use it in each
place instead.
This fixes sparse warnings like:
sound/isa/sb/sb16_main.c:61:44: warning: restricted snd_pcm_format_t degrades
to integer
