Use drmm_universal_plane_alloc() to align plane memory lifetime with the drm device. drm_plane_cleanup() is called automatically before the memory is freed. Also move the call to ipu_plane_get_resources() into ipu_plane_init() and use drm managed resources to put IPU resources automatically when required. Handle error return values of the plane property creation functions. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch>
