ALSA: aloop: Fix PCM format assignment
Fix sparse warnings about PCM format assignment regarding the strong typed snd_pcm_format_t: sound/drivers/aloop.c:352:45: warning: restricted snd_pcm_format_t degrades to integer sound/drivers/aloop.c:355:39: warning: incorrect type in assignment (different base types) sound/drivers/aloop.c:355:39: expected unsigned int format sound/drivers/aloop.c:355:39: got restricted snd_pcm_format_t [usertype] format sound/drivers/aloop.c:1435:34: warning: incorrect type in assignment (different base types) sound/drivers/aloop.c:1435:34: expected long max sound/drivers/aloop.c:1435:34: got restricted snd_pcm_format_t [usertype] sound/drivers/aloop.c:1565:39: warning: incorrect type in assignment (different base types) sound/drivers/aloop.c:1565:39: expected unsigned int format sound/drivers/aloop.c:1565:39: got restricted snd_pcm_format_t [usertype] Some code in this driver assigns an integer value to snd_pcm_format_t via control API, and they need to be with the explicit cast. No functional changes, just sparse warning fixes. Link: https://lore.kernel.org/r/20200206163945.6797-2-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
