This is a note to let you know that I've just added the patch titled net: dsa: Add missing of_node_put() in dsa_port_parse_of to the 4.19-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: net-dsa-add-missing-of_node_put-in-dsa_port_parse_of.patch and it can be found in the queue-4.19 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit db6b13edc094431b6d97b180955e3e61b8bb6337 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.
