Pull drm fixes from Dave Airlie:
 "While I hoped things would calm down, the world hasn't joined with me,
  but it's a few things scattered over a wide area. The i915 workarounds
  regression fix is probably the largest, the rest are more usual sized.
  We also get some new AMD PCI IDs.

  There is also a patch in here to MAINTAINERS to added Daniel as an
  official DRM toplevel co-maintainer, he's decided he wants to step up
  and share the glory, and he'll likely process next weeks fixes while
  I'm away on holidays.

  Summary:

  amdgpu:

   - some new PCI IDs

   - fixed firmware image updates

   - power management fixes

   - locking warning fix

  nouveau:

   - framebuffer flushing fix

   - memory leak fix

   - tegra device init regression fix

  vmwgfx:

   - OOM kernel memory fix

   - excess return in function fix

  i915:

   - the biggest fix is a regression fix where workarounds weren't
     getting reapplied after a gpu hang causing further crashing, this
     fixes the workaround application to make it happen again

   - GPU hang fixes for Braswell and some GEN3 GPUs

   - GVT fix for broadwell tiling

  rockchip:

   - revert to fix a regression causing a WARN on shutdown

  mediatek:

   - avoid crash attaching to non-existant bridges"
