Merge tag 'drm-fixes-2023-11-17' of git://anongit.freedesktop.org/drm/drm

Pull drm fixes from Daniel Vetter:
 "This is a 'blast from the bast' fixes pull, because it contains a
  bunch of AGP fixes for amdgpu. Otherwise nothing out of the ordinary.

  Next week is back to Dave unless he's knocked out by some conference
  bug.

   - amdgpu: fixes all over, including a set of AGP fixes

   - nouvea: GSP + other bugfixes

   - ivpu build fix

   - lenovo legion go panel orientation quirk"
