Pushed the following patch to drm-misc-next:

drm/atomic: Add __drm_atomic_helper_plane_reset
drm: mali-dp: Use __drm_atomic_helper_plane_reset instead of copying the logic
drm: atmel-hlcdc: Use __drm_atomic_helper_plane_reset instead of copying the logic
drm/imx: Use __drm_atomic_helper_plane_reset instead of copying the logic
drm/sun4i: Use __drm_atomic_helper_plane_reset instead of copying the logic

Thank you,
Alex Gheorghe.
