Subject: [PATCH] ALSA: pcm_dmaengine: Use pcm_for_each_format() macro for PCM format iteration
Git-commit: 89e0b9a060febbf85b985d2f3aa6afea3473276e
Patch-mainline: v5.7-rc1
References: jsc#SLE-16518
The new macro can fix the sparse warnings gracefully:
sound/core/pcm_dmaengine.c:429:50: warning: restricted snd_pcm_format_t degrades to integer
sound/core/pcm_dmaengine.c:429:55: warning: restricted snd_pcm_format_t degrades to integer
sound/core/pcm_dmaengine.c:429:79: warning: restricted snd_pcm_format_t degrades to integer
No functional changes, just sparse warning fixes.
