Subject: [PATCH AUTOSEL 4.9 07/11] ARM: hisi: Add missing of_node_put after of_find_compatible_node
Date: Wed, 1 Jun 2022 10:00:56 -0400 [thread overview]
Message-ID: <20220601140100.2005469-7-sashal@kernel.org> (raw)
In-Reply-To: <20220601140100.2005469-1-sashal@kernel.org>
From: Peng Wu <wupeng58@huawei.com>
[ Upstream commit 9bc72e47d4630d58a840a66a869c56b29554cfe4 ]
of_find_compatible_node will increment the refcount of the returned
device_node. Calling of_node_put() to avoid the refcount leak
