      drm/syncobj: Fix compilation following partial revert · 91324069
      Chris Wilson authored
      We need to include the revert of commit 783195ec ("drm/syncobj:
      disable the timeline UAPI for now v2") along with undoing the change to
      drm/i915.
      
      Fixes: 131280a1 ("drm: Revert syncobj timeline changes.")

      drm: Revert syncobj timeline changes. · 131280a1
      Eric Anholt authored
      Daniel suggested I submit this, since we're still seeing regressions
      from it.  This is a revert to before 48197bc5 ("drm: add syncobj
      timeline support v9") and its followon fixes.
      
      Fixes this on first V3D testcase execution:
