Subject[PATCH 4.14 025/173] ALSA: dummy: Fix PCM format loop in proc output
Date
From: Takashi Iwai <tiwai@suse.de>

commit 2acf25f13ebe8beb40e97a1bbe76f36277c64f1e upstream.

The loop termination for iterating over all formats should contain
SNDRV_PCM_FORMAT_LAST, not less than it.

Fixes: 9b151fec139d ("ALSA: dummy - Add debug proc file")
