4.9-stable review patch. If anyone has any objections, please let me know.
------------------ From: Tyrel Datwyler <[email protected]> commit b8475cbee5ab2eac05f9cd5dbcc94c453d3cbf10 upstream. The call to of_find_node_by_path("/cpus") returns the cpus device_node with its reference count incremented. There is no matching of_node_put() call in of_numa_parse_cpu_nodes() which results in a leaked reference to the "/cpus" node. This patch adds an of_node_put() to release the reference. fixes: 298535c00a2c ("of, numa: Add NUMA of binding implementation.")
