Merge tag 'drm-next-2025-10-11-1' of https://gitlab.freedesktop.org/drm/kernel
Pull more drm fixes from Dave Airlie:
"Just the follow up fixes for rc1 from the next branch, amdgpu and xe
mostly with a single v3d fix in there.
amdgpu:
- DC DCE6 fixes
- GPU reset fixes
- Secure diplay messaging cleanup
- MES fix
- GPUVM locking fixes
- PMFW messaging cleanup
- PCI US/DS switch handling fix
- VCN queue reset fix
- DC FPU handling fix
- DCN 3.5 fix
- DC mirroring fix
amdkfd:
- Fix kfd process ref leak
- mmap write lock handling fix
- Fix comments in IOCTL
xe:
- Fix build with clang 16
- Fix handling of invalid configfs syntax usage and spell out the
expected syntax in the documentation
- Do not try late bind firmware when running as VF since it shouldn't
handle firmware loading
- Fix idle assertion for local BOs
- Fix uninitialized variable for late binding
- Do not require perfmon_capable to expose free memory at page
granularity. Handle it like other drm drivers do
- Fix lock handling on suspend error path
- Fix I2C controller resume after S3
v3d:
- fix fence locking"
