Subject: drm/amd/display: Use dc_update_planes_and_stream
From: Rodrigo Siqueira <Rodrigo.Siqueira@xxxxxxx>
commit f7511289821ffccc07579406d6ab520aa11049f5 upstream.
[Why & How]
The old dc_commit_updates_for_stream lacks manipulation for many corner
cases where the DC feature requires special attention; as a result, it
starts to show its limitation (e.g., the SubVP feature is not supported
by it, among other cases). To modernize and unify our internal API, this
commit replaces the old dc_commit_updates_for_stream with
dc_update_planes_and_stream, which has more features.
