Subject: [PATCH] net: dsa: Add missing of_node_put() in dsa_port_parse_of
Date: Wed, 16 Mar 2022 08:26:02 +0000 [thread overview]
Message-ID: <20220316082602.10785-1-linmq006@gmail.com> (raw)
The device_node pointer is returned by of_parse_phandle() with refcount
incremented. We should use of_node_put() on it when done.
Fixes: 6d4e5c570c2d ("net: dsa: get port type at parse time")
