Subject: [PATCH AUTOSEL 5.4 19/24] drm/vc4: drv: Add error handding for bind
Date: Mon, 2 Nov 2020 20:20:02 -0500 [thread overview]
Message-ID: <20201103012007.183429-19-sashal@kernel.org> (raw)
In-Reply-To: <20201103012007.183429-1-sashal@kernel.org>
From: Hoegeun Kwon <hoegeun.kwon@samsung.com>
[ Upstream commit 9ce0af3e9573fb84c4c807183d13ea2a68271e4b ]
There is a problem that if vc4_drm bind fails, a memory leak occurs on
the drm_property_create side. Add error handding for drm_mode_config.
