[PATCH 3.18 19/31] drivers/tty: add missing of_node_put()

From: Greg Kroah-Hartman
Date: Thu Dec 20 2018 - 04:20:01 EST


3.18-stable review patch. If anyone has any objections, please let me know.

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

[ Upstream commit dac097c4546e4c5b16dd303a1e97c1d319c8ab3e ]

of_find_node_by_path() acquires a reference to the node
returned by it and that reference needs to be dropped by its caller.
This place is not doing this, so fix it.
