4.9-stable review patch. If anyone has any objections, please let me know.
------------------ From: Daniel Vetter <[email protected]> [ Upstream commit ae9d2daecf086958a41ad216152ec208d70ba325 ] fsl is already fully demidlayered in the probe function, but for convenience stuck with drm_put_dev. Call the unregister/unref parts separately, to make sure this driver works correct.
