Subject: [PATCH] ALSA: usb-audio: Use pcm_for_each_format() macro for PCM format iterations
Git-commit: 5b29f05396bde54788a18633155ffa3f4d745f0d
Patch-mainline: v5.7-rc1
References: jsc#SLE-16518
The new macro can fix the sparse warnings gracefully:
sound/usb/proc.c:73:31: warning: restricted snd_pcm_format_t degrades to integer
sound/usb/proc.c:73:38: warning: restricted snd_pcm_format_t degrades to integer
sound/usb/proc.c:73:61: warning: restricted snd_pcm_format_t degrades to integer
No functional changes, just sparse warning fixes.
