Subject: [PATCH] drm/i915/selftests: exercise_ggtt may have nothing to do
Git-commit: 4fe95b042d9d36744f6848069a92759c10dd2a0e
Patch-mainline: v4.16-rc1
References: FATE#322643 bsc#1055900
When operating on the live_ggtt we have to find a usuable hole for our
test. It is possible for there to be no hole we can use, so initialise
the err to 0 for the early exit.
