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

Pull drm fixes from Dave Airlie:
 "Nothing major in here, one radeon SI fix for tiling, and one uninit
  var fix, two minor header file fixes."

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
  drm: drop comment about this header being autogenerated.
  drm/edid: don't return stack garbage from supports_rb
  vga_switcheroo: Add include guard
  drm/radeon: SI tiling fixes for display
