Subject: [PATCH] drm/i915: remove redundant warnings
Date: Fri, 2 Dec 2016 10:58:38 +0000 [thread overview]
Message-ID: <20161202105838.21274-1-matthew.auld@intel.com> (raw)
If we've gotten this far then we must have already checked if the
vma can fit into the vm when we inserted the mm node, and in turn
must have also checked for the overflow.
