stable inclusion from stable-v5.10.110 commit 72ea0fefea18b8b0e1309187098d4ec74bc057ac bugzilla: https://gitee.com/openeuler/kernel/issues/I574AL
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
[ Upstream commit dab4df9ca919f59e5b9dd84385eaf34d4f20dbb0 ]
The device_node pointer is returned by of_parse_phandle() with refcount incremented. We should use of_node_put() on it when done.
