stable inclusion from stable-v5.10.121 commit 46fd994763cf6884b88a2da712af918f3ed54d7b category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I5L6CQ

--------------------------------
[ Upstream commit fcee96924ba1596ca80a6770b2567ca546f9a482 ]
of_parse_phandle() returns a node pointer with refcount incremented, we should use of_node_put() on it when not need anymore. Add missing of_node_put() to avoid refcount leak.
