From 6d3d23c57b33d76f0b4f01221593182c0de34ef4 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Mon, 25 Jul 2016 16:10:04 -0700 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 Fixes: d5b1a78a772f ("drm/vc4: Add support for drawing 3D frames.")
