Subject: [PATCH 5.4 10/17] net: dsa: Add missing of_node_put() in dsa_port_parse_of
Date: Mon, 21 Mar 2022 14:52:46 +0100 [thread overview]
Message-ID: <20220321133217.455384427@linuxfoundation.org> (raw)
In-Reply-To: <20220321133217.148831184@linuxfoundation.org>
From: Miaoqian Lin <linmq006@gmail.com>
[ 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.
Fixes: 6d4e5c570c2d ("net: dsa: get port type at parse time")
