[PATCH] drm/of: Fix device node reference leak in drm_of_panel_bridge_remove

[Miaoqian Lin]

of_graph_get_remote_node() returns a device node
with its reference count incremented. The caller is responsible for
releasing this reference when the node is no longer needed.

Add of_node_put(remote) to fix the reference leak.

Found via static analysis.
