[ Upstream commit 7f500f2011c0bbb6e1cacab74b4c99222e60248e ]
of_get_next_child() will increase refcount of the returned node, need
use of_node_put() on it when done.
Per current implementation, 'child' will be override by
for_each_child_of_node(np, child), so use of_get_child_count to avoid
refcount leakage.
