Subject: [PATCH] drm/i915: check vma for error in ggtt_unpin_view
Date: Wed, 23 Mar 2016 15:39:44 +0000 [thread overview]
Message-ID: <1458747584-29772-1-git-send-email-matthew.auld@intel.com> (raw)
When unpinning a ggtt_view check vma for error, otherwise we may end up
accessing an invalid pointer.
