Pull drm fixes from Dave Airlie:
 "Fixes for rc7, bit bigger than I'd like at this stage, but most of the
  i915 stuff and some amdgpu is destined for staging and I'd rather not
  hold it up, the i915 changes also pulled in a few precusor code
  movement patches to make things cleaner, but nothing seems that
  horrible, and I've checked over all of it.

  Otherwise there is a nouveau dma-api warning regression, and a ttm
  page allocation warning fix, and some fixes for a bridge chip,

  ttm:
   - fix huge page warning regression

  i915:
   - Skip vswing programming for TBT
   - Power up combo PHY lanes for HDMI
   - Fix double YUV range correction on HDR planes
   - Fix the MST PBN divider calculation
   - Fix LTTPR vswing/pre-emp setting in non-transparent mode
   - Move the breadcrumb to the signaler if completed upon cancel
   - Close race between enable_breadcrumbs and cancel_breadcrumbs
   - Drop lru bumping on display unpinning

  amdgpu:
   - Fix retry in gem create
   - Vangogh fixes
   - Fix for display from shared buffers
   - Various display fixes

  amdkfd:
   - Fix regression in buffer free

  nouveau:
   - fix DMA API warning regression

  drm/bridge/lontium-lt9611uxc:
   - EDID fixes
   - Don't handle hotplug events in IRQ handler"
