4.7-stable review patch. If anyone has any objections, please let me know.
------------------
From: Eric Anholt <eric@xxxxxxxxxx>
commit 552416c146fadc67cd9b53ef7adf88d3381c43a6 upstream.
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@xxxxxxxxxx>
Fixes: d5b1a78a772f ("drm/vc4: Add support for drawing 3D frames.")
