[PATCH] drm/i915: Call intel_opregion_notify_encoder in intel_sanitize_encoder

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

 



Normally this is called on a modeset, but the call is missing when
we inherit the mode from the BIOS, so make sure it's called somewhere
in hardware readout.
