Pull drm fixes from Dave Airlie:
 "Pretty quiet week, just some amdgpu and i915 fixes.

  i915:
   - deadlock fix
   - gvt fixes

  amdgpu:
   - PCIE dpm feature fix
   - Powerplay fixes"

* tag 'drm-fixes-2019-04-05' of git://anongit.freedesktop.org/drm/drm:
  drm/i915/gvt: Fix kerneldoc typo for intel_vgpu_emulate_hotplug
  drm/i915/gvt: Correct the calculation of plane size
  drm/amdgpu: remove unnecessary rlc reset function on gfx9
  drm/i915: Always backoff after a drm_modeset_lock() deadlock
  drm/i915/gvt: do not let pin count of shadow mm go negative
  drm/i915/gvt: do not deliver a workload if its creation fails
  drm/amd/display: VBIOS can't be light up HDMI when restart system
  drm/amd/powerplay: fix possible hang with 3+ 4K monitors
  drm/amd/powerplay: correct data type to avoid overflow
  drm/amd/powerplay: add ECC feature bit
  drm/amd/amdgpu: fix PCIe dpm feature issue (v3)
