Pull drm fixes from Dave Airlie:
 "I really need to get back to sending these on my Friday, instead of my
  Monday morning, but nothing too amazing in here: a few amdkfd fixes, a
  few radeon fixes, i915 fixes, one tegra fix and one core fix"

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
  drm: Zero out invalid vblank timestamp in drm_update_vblank_count.
  drm/tegra: Don't use vblank_disable_immediate on incapable driver.
  drm/radeon: stop trying to suspend UVD sessions
  drm/radeon: more strictly validate the UVD codec
  drm/radeon: make UVD handle checking more strict
  drm/radeon: make VCE handle check more strict
  drm/radeon: fix userptr lockup
  drm/radeon: fix userptr BO unpin bug v3
  drm/amdkfd: Initialize sdma vm when creating sdma queue
  drm/amdkfd: Don't report local memory size
  drm/amdkfd: allow unregister process with queues
  drm/i915: Drop PIPE-A quirk for 945GSE HP Mini
  drm/i915: Sink rate read should be saved in deca-kHz
  drm/i915/dp: there is no audio on port A
  drm/i915: Add missing MacBook Pro models with dual channel LVDS
  drm/i915: Assume dual channel LVDS if pixel clock necessitates it
  drm/radeon: don't setup audio on asics that don't support it
  drm/radeon: disable semaphores for UVD V1 (v2)
