[PATCH AUTOSEL 3.18 09/16] drivers/tty: add missing of_node_put()

[Sasha Levin]

From: Yangtao Li <tiny.windzz@xxxxxxxxx>

[ 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.
