Merge branch 'drm-intel-fixes' of git://people.freedesktop.org/~danvet/drm-intel into drm-fixes

Daniel Vetter writes"
Nothing big at all for -fixes, just small stuff:
- Two patches to fix bugs on i830M
- ums regression fixer due to kicking firmeware fbs (Chris)
- tune down a too loud warning (Jani)
- be more careful with sdvo infoframes, which fixes a long-standing
  sdvo-hdmi regression"

* 'drm-intel-fixes' of git://people.freedesktop.org/~danvet/drm-intel:
  drm/i915: Only kick out vesafb if we takeover the fbcon with KMS
  drm/i915: be less verbose about inability to provide vendor backlight
  drm/i915: clear the entire sdvo infoframe buffer
  drm/i915: VGA needs to be on pipe A on i830M
  drm/i915: fix overlay on i830M
