[PATCH 3/4] drm/i915/display: Remove some redundancy around CAN_PSR()

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

 



If source_support is set the platform supports PSR so no need to check
it again at every CAN_PSR().

Also removing the intel_dp_is_edp() calls, if sink_support is set
the sink connected is for sure a eDP panel.
