[PATCH 3.16 90/99] ALSA: dummy: Fix PCM format loop in proc output

From: Ben Hutchings
Date: Wed May 20 2020 - 10:25:46 EST


3.16.84-rc1 review patch. If anyone has any objections, please let me know.

------------------

From: Takashi Iwai <tiwai@xxxxxxx>

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")
