[PATCH 17/43] drm/amd/display: Add OTG check for set AV mute

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


From: "Leo (Hanghong) Ma" <hanghong.ma@xxxxxxx>

[Why && How]
OTG can be disabled before setting dpms on. Add check to skip wait
when setting AV mute if OTG is disabled.
