3.16.52-rc1 review patch. If anyone has any objections, please let me know.

From: Tyrel Datwyler tyreld@linux.vnet.ibm.com
commit b537ca6fede69a281dc524983e5e633d79a10a08 upstream.
A reference to the parent device node is held by add_dt_node() for the node to be added. If the call to dlpar_configure_connector() fails add_dt_node() returns ENOENT and that reference is not freed.
Add a call to of_node_put(parent_dn) prior to bailing out after a failed dlpar_configure_connector() call.
