Subject: [PATCH AUTOSEL 4.14 09/10] drm/vc4: drv: Add error handding for bind

From: Hoegeun Kwon <hoegeun.kwon@...sung.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.
