Subject: [PATCH 4.14 091/284] video: fbdev: omapfb: Add missing of_node_put() in dvic_probe_of
From: Miaoqian Lin <linmq006@...il.com>
[ Upstream commit a58c22cfbbf62fefca090334bbd35fd132e92a23 ]
The device_node pointer is returned by of_parse_phandle() with refcount
incremented. We should use of_node_put() on it when done.
Fixes: f76ee892a99e ("omapfb: copy omapdss & displays for omapfb")
