Subject: drivers/tty: add missing of_node_put()
X-Git-Tag: v4.20-rc6~43^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=dac097c4546e4c5b16dd303a1e97c1d319c8ab3e;p=thirdparty%2Fkernel%2Flinux.git

drivers/tty: add missing of_node_put()

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.
