If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit f1ec2ae9b25ad9c01f5b5de27a4145576c034925 Author: Miaoqian Lin <linmq006@xxxxxxxxx> Date: Wed Mar 16 08:26:02 2022 +0000 net: dsa: Add missing of_node_put() in dsa_port_parse_of [ Upstream commit cb0b430b4e3acc88c85e0ad2e25f2a25a5765262 ] The device_node pointer is returned by of_parse_phandle() with refcount incremented. We should use of_node_put() on it when done.
