Pull drm fixes from Dave Airlie:
 "Scattered selection of fixes:

   - radeon: load detect fixes from SuSE/AMD
   - intel: misc i830, sdvo regression, vesafb kickoff ums fix
   - exynos: maintainers entry update + fixes
   - udl: fix stride scanout issue

  it's slightly bigger than I'd probably like, but nothing looked
  dangerous enough to hold off on."
