ALSA: dummy: Use standard macros for fixing PCM format cast
Simplify the code with the new macros for PCM format type iterations. This fixes the sparse warnings nicely: sound/drivers/dummy.c:906:25: warning: restricted snd_pcm_format_t degrades to integer sound/drivers/dummy.c:908:25: warning: incorrect type in argument 1 (different base types) sound/drivers/dummy.c:908:25: expected restricted snd_pcm_format_t [usertype] format sound/drivers/dummy.c:908:25: got int [assigned] i No functional changes, just sparse warning fixes.
