Subject: drm/mediatek: don't use drm_put_dev

From: Daniel Vetter <daniel.vetter@ffwll.ch>


[ 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.
