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"
