drm/plane: Pass old state to ->atomic_update()
In most situations it will be useful to have the old state passed to the ->atomic_update() callback. For example if a plane is being disabled the new state's .crtc field will be NULL, but some drivers may rely on this field to program the CRTCs registers. v2: rename variable to old_plane_state and remove redundant comment as suggested by Daniel Vetter, remove an Exynos hunk that doesn't apply to drm-next and add a hunk for pending MSM mdp5 changes Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
