* 'drm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/airlied/drm-2.6:
  vgaarb: Wrap vga_(get|put) in CONFIG_VGA_ARB
  drm/radeon/kms: add missing scratch update in dp_detect
  drm/modes: Fix CVT-R modeline generation
  drm: fix regression in drm locking since BKL removal.
  drm/radeon/kms: remove stray radeon_i2c_destroy
  drm: mm: fix range restricted allocations
  drm/nouveau: drop drm_global_mutex before sleeping in submission path
  drm: export drm_global_mutex for drivers to use
  drm/nv20: Don't use pushbuf calls on the original nv20.
  drm/nouveau: Fix TMDS on some DCB1.5 boards.
  drm/nouveau: Fix backlight control on PPC machines with an internal TMDS panel.
  drm/nv30: Apply modesetting to the correct slave encoder
  drm/nouveau: Use a helper function to match PCI device/subsystem IDs.
  drm/nv50: add dcb type 14 to enum to prevent compiler complaint
