Subject: [PATCH] mips: ralink: Fix refcount leak in of.c
Date: Fri, 17 Jun 2022 11:39:29 +0800 [thread overview]
Message-ID: <20220617033929.4002832-1-windhl@126.com> (raw)
In plat_of_remap_node(), plat_of_remap_node() will return a node
pointer with refcount incremented. We should use of_node_put()
when it is not used anymore.
