Merge tag 'drm-next-2021-09-10' of git://anongit.freedesktop.org/drm/drm
Pull drm fixes from Dave Airlie:
"Just an initial bunch of fixes for the merge window, amdgpu is most of
them with a few ttm fixes and an fbdev avoid multiply overflow fix.
core:
- Make some dma-buf config options depend on DMA_SHARED_BUFFER
- Handle multiplication overflow of fbdev xres/yres in the core
ttm:
- Fix ttm_bo_move_memcpy() when ttm_resource is subclassed
- Fix ttm deadlock if target BO isn't idle
- ttm build fix
- ttm docs fix
dma-buf:
- config option fixes
fbdev:
- limit resolutions to avoid int overflow
i915:
- stddef change.
amdgpu:
- Misc cleanups, typo fixes
- EEPROM fix
- Add some new PCI IDs
- Scatter/Gather display support for Yellow Carp
- PCIe DPM fix for RKL platforms
- RAS fix
amdkfd:
- SVM fix
vc4:
- static function fix
mgag200:
- fix uninit var
panfrost:
- lock_region fixes"
