Pull drm fixes from Dave Airlie:
 "i915 and radeon fixes:

  i915:
      fix for connector oops regression
      DDC probing fix

  radeon:
      two radeon reverts, along with a freeze workaround and a fix"

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
  drm/radeon: Make sure radeon_vm_bo_set_addr always unreserves the BO
  Revert "drm/radeon: adjust pll when audio is not enabled"
  Revert "drm/radeon: don't share plls if monitors differ in audio support"
  drm/radeon: fix freeze for laptop with Turks/Thames GPU.
  drm/i915: Fix DDC probe for passive adapters
  drm/i915: Properly initialize SDVO analog connectors
