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

Pull drm fixes from Dave Airlie:
 "Unfortunately this contains no easter eggs, its a bit larger than I'd
  like, but I included a patch that just moves code from one file to
  another and I'd like to avoid merge conflicts with that later, so it
  makes it seem worse than it is,

  Otherwise:
   - radeon: fixes to use new microcode to stabilise some cards, use
     some common displayport code, some runtime pm fixes, pll regression
     fixes
   - i915: fix for some context oopses, a warn in a used path, backlight
     fixes
   - nouveau: regression fix
   - omap: a bunch of fixes"

/**
* DOC: output probing helper overview
*
* This library provides some helper code for output probing. It provides an
* implementation of the core connector->fill_modes interface with
* drm_helper_probe_single_connector_modes.
*
* It also provides support for polling connectors with a work item and for
* generic hotplug interrupt handling where the driver doesn't or cannot keep
* track of a per-connector hpd interrupt.
*
* This helper library can be used independently of the modeset helper library.
* Drivers can also overwrite different parts e.g. use their own hotplug
* handling code to avoid probing unrelated outputs.
