Subject: [PATCH 4.9 18/51] net: amd: add missing of_node_put()

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

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

[ Upstream commit c44c749d3b6fdfca39002e7e48e03fe9f9fe37a3 ]

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 doesn't do that, so fix it.
