+Subject: [PATCH] drm/vc4: Fix oops when userspace hands in a bad BO.
+
+We'd end up NULL pointer dereferencing because we didn't take the
+error path out in the parent.  Fixes igt vc4_lookup_fail test.

+Signed-off-by: Eric Anholt <eric@anholt.net>
+Fixes: d5b1a78a772f ("drm/vc4: Add support for drawing 3D frames.")
