Subject: [PATCH] ALSA: dummy: Fix PCM format loop in proc output
Git-commit: 2acf25f13ebe8beb40e97a1bbe76f36277c64f1e
Patch-mainline: v5.6-rc1
References: bsc#1111666
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")
