From: Daniel Vetter Date: Fri, 14 Feb 2014 13:01:19 +0000 (+0100) Subject: drm/i915: Simplify i915_gem_object_ggtt_unpin X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b287110e890e3f11ce3671305215eb1c8d791de2;p=openwrt%2Fstaging%2Fblogic.git drm/i915: Simplify i915_gem_object_ggtt_unpin Split out from Chris vma-bind rework. Jani wondered why this is save, and the reason is that i915_vma_unbind does all these checks, too. So they're redundant.
