drm/omap: check if rotation is supported before commit
omapdrm is missing a check on the validity of the rotation property. This leads to omapdrm possibly trying to use rotation on non-rotateable framebuffer, which causes the overlay setup to fail. This patch adds the necessary check to omap_plane_atomic_check(). Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
