| Subject: [PATCH] ALSA: dummy: Fix PCM format loop in proc output |
| |
| 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") |
