+Subject: [PATCH] drm/amd/display: let update_planes_and_stream_state defines
+ minimal state
+
+We see artifacts when using current state as the minimal one in a
+context where update_planes_and_stream_state set the update type as
+FULL. Therefore, instead of define the minimal state by adding or
+removing planes, let update_planes_and_stream_state define the proper
+state.
