[PATCH 08/11] drm/amd/display: Do full modeset when DSC debugfs is changed

[Aurabindo Pillai]

From: Eryk Brol <eryk.brol at amd.com>

[Why]
Whenever DSC parameters are changed we need to perform full modeset to commit
DSC changes to DC.

[How]
If dsc_force_changed is set, need to set mode_changed on new CRTC state
