| Subject: ALSA: seq: ump: Fix -Wformat-truncation warning |
| |
| From: Takashi Iwai <tiwai@suse.de> |
| |
| [ Upstream commit 0d42260867f9ff3e3a5bcfa8750fa06a658e0b1c ] |
| |
| The filling of a port name string got a warning with W=1 due to the |
| potentially too long group name. Add the string precision to limit |
| the size. |
| |
| Fixes: 81fd444aa371 ("ALSA: seq: Bind UMP device") |
