Subject: [PATCH 4.9 09/30] mips: lantiq: xway: Fix refcount leak bug in sysctrl
Date: Mon, 26 Sep 2022 12:11:40 +0200	[thread overview]
Message-ID: <20220926100736.491653664@linuxfoundation.org> (raw)
In-Reply-To: <20220926100736.153157100@linuxfoundation.org>

From: Liang He <windhl@126.com>

[ Upstream commit 76695592711ef1e215cc24ed3e1cd857d7fc3098 ]

In ltq_soc_init(), of_find_compatible_node() will return a node
pointer with refcount incremented. We should use of_node_put() when
it is not used anymore.
