From 8b56d3d8f87edb05be6ad93d2081a6147eef46f4 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Christian=20K=C3=B6nig?= Date: Wed, 21 Mar 2018 13:58:05 +0100 Subject: [PATCH] drm/amdgpu: fix "mitigate workaround for i915" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Mixed up exporter and importer here. E.g. while mapping the BO we need to check the importer not the exporter.
