Many drm connectors do not need mode validation. The patch makes this callback optional and removes dumb implementations. v2: Rebase: - imx move to a shared (but still dummy) ->mode_valid implementation. - probe helpers have been extracted to drm_probe_helper.c Signed-off-by: Andrzej Hajda <a.hajda@samsung.com> (v1) Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
