Merge drm/drm-next into drm-intel-gt-next
In order to get the GSC Support merged on drm-intel-gt-next
in a clean fashion we needed this ATS-M patch to avoid
conflict in i915_pci.c:
commit 412c942bdfae ("drm/i915/ats-m: add ATS-M platform info")
--
Fixing a silent conflict on drivers/gpu/drm/i915/gt/intel_gt_gmch.c:
- if (!intel_vtd_active(i915))
+ if (!i915_vtd_active(i915))
