Merge tag 'drm-fixes-2018-07-06' of git://anongit.freedesktop.org/drm/drm

Pull drm fixes from Dave Airlie:
 "This is the drm fixes for rc4.

  It's a bit larger than I'd like but the exynos cleanups are pretty
  mechanical, and I'd rather have them in sooner rather than later so we
  can avoid too much conflicts around them. The non-mechanincal exynos
  changes are mostly fixes for new feature recently introduced.

  Apart from the exynos updates, we have:

  i915:
   - GVT and GGTT mapping fixes

  amdgpu:
   - fix HDMI2.0 4K@60 Hz regression
   - Hotplug fixes for dual-GPU laptops to make power management better
   - misc vega12 bios fixes, a race fix and some typos.

  sii8620 bridge:
   - small fixes around mode setting

  core:
   - use kvzalloc to allocate blob property memory"
