From: Chris Wilson Date: Sun, 5 Nov 2017 12:45:50 +0000 (+0000) Subject: drm/i915: Assert vma->flags are updated correctly during binding X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=d36caeea4b0f76bf691c7d0cddc4a71ed93783c5;p=openwrt%2Fstaging%2Fblogic.git drm/i915: Assert vma->flags are updated correctly during binding As we bind, and unbind on error, we want to be sure that the vma->flags are updated to reflect the binding state so that on the next invocation all is well. v2: Take two. v3: Take three; vma-misplaced is checking map-and-fenceable so keep it last!
