From: Liang He <windhl@126.com> [ Upstream commit e0686dc6f2252e009c455fe99e2ce9d62a60eb47 ] The reference 'child' in the iteration of for_each_available_child_of_node() is only escaped out into a local variable which is only used to check its value. So we still need to the of_node_put() when breaking of the for_each_available_child_of_node() which will automatically increase and decrease the refcount.
