Subject: of: fix "/cpus" reference leak in of_numa_parse_cpu_nodes()
From: Tyrel Datwyler <tyreld@xxxxxxxxxxxxxxxxxx>
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.")
