Subject[PATCH 5/7] drm/mediatek: plane: Merge mtk_plane_enable into mtk_plane_atomic_update
Date
From: Daniel Kurtz <djkurtz@chromium.org>

The mtk_plane_enable is just called once by mtk_plane_atomic_update.
So, merge mtk_plane_enable into mtk_plane_atomic_update.

While we are here, also clean up the function a bit by using an fb local
variables.
