Subject: [PATCH AUTOSEL 4.14 07/12] ARM: OMAP2+: display: Fix refcount leak bug
Date: Sun, 7 Aug 2022 21:39:37 -0400 [thread overview]
Message-ID: <20220808013943.316907-7-sashal@kernel.org> (raw)
In-Reply-To: <20220808013943.316907-1-sashal@kernel.org>
From: Liang He <windhl@126.com>
[ Upstream commit 50b87a32a79bca6e275918a711fb8cc55e16d739 ]
In omapdss_init_fbdev(), of_find_node_by_name() will return a node
pointer with refcount incremented. We should use of_node_put() when
it is not used anymore.
