Merge tag 'drm-next-2023-11-10' of git://anongit.freedesktop.org/drm/drm
Pull drm fixes from Daniel Vetter:
"Dave's VPN to the big machine died, so it's on me to do fixes pr this
and next week while everyone else is at plumbers.
- big pile of amd fixes, but mostly for hw support newly added in 6.7
- i915 fixes, mostly minor things
- qxl memory leak fix
- vc4 uaf fix in mock helpers
- syncobj fix for DRM_SYNCOBJ_WAIT_FLAGS_WAIT_AVAILABLE"
