This problem seems to come from the fact that only the PR from yesterday that got merged to drm-next had the dependency patches. The previous backmerge of drm-next was requested too early. I've solved this with least hassle by backmerging drm-next again and then applying the PR to drm-intel-gt-next. I think drm-misc-next should do the same (exact commit was 1bd8a7dc28c1c410f1ceefae1f2a97c06d1a67c2).
