| Subject: ALSA: x86: Fix missing spinlock and mutex initializations |
| |
| From: Takashi Iwai <tiwai@suse.de> |
| |
| commit 350144069abf351c743d766b2fba9cb9b7cd32a1 upstream. |
| |
| The commit change for supporting the multiple ports moved involved |
| some code shuffling, and there the initializations of spinlock and |
| mutex in snd_intelhad object were dropped mistakenly. |
| |
| This patch adds the missing initializations again for each port. |
| |
| Fixes: b4eb0d522fcb ("ALSA: x86: Split snd_intelhad into card and PCM specific structures") |
