Subject: [PATCH] drm/vc4: drv: Add error handding for bind

Git-commit: 9ce0af3e9573fb84c4c807183d13ea2a68271e4b

Patch-mainline: v5.10-rc2

References: git-fixes

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.
