Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux 

Pull drm fixes from Dave Airlie:
 "Intel and radeon fixes.

  Post KS/LC git requests from i915 and radeon stacked up.  They are all
  fixes along with some new pci ids for radeon, and one maintainers file
  entry.

   - i915: display fixes and irq fixes
   - radeon: pci ids, and misc gpuvm, dpm and hdp cache"
