If anyone has any objections, please let me know. ------------------ From: Fabrizio Castro [ Upstream commit 391b41f983bf7ff853de44704d8e14e7cc648a9b ] of_parse_phandle_with_fixed_args() requires its caller to call into of_node_put() on the node pointer from the output structure, but such a call is currently missing. Call into of_node_put() to rectify that.
