drm: of: drm_of_panel_bridge_remove(): fix device_node leak
[ Upstream commit a4b4385d0523e39a7c058cb5a6c8269e513126ca ]
drm_of_panel_bridge_remove() uses of_graph_get_remote_node() to get a
device_node but does not put the node reference.
Fixes: c70087e8f16f ("drm/drm_of: add drm_of_panel_bridge_remove function")
Cc: stable@vger.kernel.org # v4.15
