    Subject[PATCH AUTOSEL 4.19 30/73] drivers/tty: add missing of_node_put()
    Date
    From: Yangtao Li <tiny.windzz@gmail.com>

    [ 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.
