3.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Tang Yuantian <yuantian.tang@xxxxxxxxxxxxx>
commit b855f16b05a697ac1863adabe99bfba56e6d3199 upstream.
Call of_node_put() only when the out_args is NULL on success,
or the node's reference count will not be correct because the caller
will call of_node_put() again.
