Subject[PATCH 4.9 120/138] drm/mediatek: dont use drm_put_dev
Date
4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

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.
