Pull drm fixes from Dave Airlie:
 "As mentioned last week an i915 PR came in late, but I left it, so the
  i915 bits of this cover 2 weeks, which is why it's likely a bit larger
  than usual.

  Otherwise it's mostly amdgpu fixes, one tegra fix, one meson fix.

  i915:
   - Handle idling during i915_gem_evict_something busy loops (Chris)
   - Mark current submissions with a weak-dependency (Chris)
   - Propagate error from completed fences (Chris)
   - Fixes on execlist to avoid GPU hang situation (Chris)
   - Fixes couple deadlocks (Chris)
   - Timeslice preemption fixes (Chris)
   - Fix Display Port interrupt handling on Tiger Lake (Imre)
   - Reduce debug noise around Frame Buffer Compression (Peter)
   - Fix logic around IPC W/a for Coffee Lake and Kaby Lake (Sultan)
   - Avoid dereferencing a dead context (Chris)

  tegra:
   - tegra120/4 smmu fixes

  amdgpu:
   - Clockgating fixes
   - Fix fbdev with scatter/gather display
   - S4 fix for navi
   - Soft recovery for gfx10
   - Freesync fixes
   - Atomic check cursor fix
   - Add a gfxoff quirk
   - MST fix

  amdkfd:
   - Fix GEM reference counting

  meson:
   - error code propogation fix"
