+Subject: [PATCH 3013/4131] drm/amd/display: reprogram surface config on
+ scaling change
+
+When plane size changes, we need to reprogram surface pitch in addition
+to viewport and scaler. This change is a conservative way to make this happen.
+However it could be more optimized to move pitch programming into
+mem_program_viewport.
