Merge drm/drm-next into drm-intel-gt-next
We need 4ba4f1afb6a9 ("perf: Generic hotplug support for a PMU with a scope") in order to land a i915 PMU simplification and a fix. That landed in 6.12 and we are stuck at 6.9 so lets bump things forward. Signed-off-by: Tvrtko Ursulin <tursulin@ursulin.net>
