Merge tag 'drm-intel-next-fixes-2018-06-08-2' of git://anongit.freedesktop.org/drm/drm-intel into drm-nextdrm-next-2018-06-11
First batch of i915 fixes for v4.18: - gvt fixes that missed v4.17, potentially need to be backported - eDP resolution regression revert - remove broken nv12 special casing - remove stale asserts from find active requests Signed-off-by: Dave Airlie <airlied@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/87y3fp4h15.fsf@intel.com
