Subject: [PATCH AUTOSEL 5.4 10/20] ARM: versatile: Add missing of_node_put in dcscb_init
Date: Wed, 1 Jun 2022 09:58:52 -0400 [thread overview]
Message-ID: <20220601135902.2004823-10-sashal@kernel.org> (raw)
In-Reply-To: <20220601135902.2004823-1-sashal@kernel.org>
From: Peng Wu <wupeng58@huawei.com>
[ Upstream commit 23b44f9c649bbef10b45fa33080cd8b4166800ae ]
The device_node pointer is returned by of_find_compatible_node
with refcount incremented. We should use of_node_put() to avoid
the refcount leak.
