From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
Currently we're leaking fbs on load detect on account of nothing setting
up plane->old_fb for the drm_atomic_clean_old_fb() call in
drm_atomic_helper_commit_duplicated_state(). Removing the
drm_atomic_clean_old_fb() call seems like the right call to me here.
This does mean we end up leaking something via
drm_atomic_helper_shutdown() though, but we'll fix that up in a
different way.
This reverts commit 49d70aeaeca8f62b72b7712ecd1e29619a445866.
