| Subject: ALSA: hda/via - Disable broken dynamic power control |
| |
| From: Takashi Iwai <tiwai@suse.de> |
| |
| commit 087c2e3b4e062573dbbc8a50b9208992e3768dcf upstream. |
| |
| Since the transition to the generic parser, the actual routes used |
| there don't match always with the assumed static paths in some |
| set_widgets_power_state callbacks. This results in the wrong power |
| setup in the end. As a temporary workaround, we need to disable the |
| calls together with the non-functional dynamic power control enum. |
