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

Browse Source 
Pull drm radeon and nouveau fixes from Dave Airlie:
 "Fixes for the other big two.

  The radeon VCE one is large but it fixes some userspace triggerable
  issues, otherwise its blackscreens and oopses.

  Nouveau fixes a bleeding laptop panel issue when displayport is used
  sometimes"

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
  drm/radeon/pm: don't allow debugfs/sysfs access when PX card is off (v2)
  drm/radeon: avoid segfault on device open when accel is not working.
  drm/radeon: fix typo in finding PLL params
  drm/radeon: fix register typo on si
  drm/radeon: fix buffer placement under memory pressure v2
  drm/radeon: fix page directory update size estimation
  drm/radeon: handle non-VGA class pci devices with ATRM
  drm/radeon: fix DCE83 check for mullins
  drm/radeon: check VCE relocation buffer range v3
  drm/radeon: also try GART for CPU accessed buffers
  drm/gf119-/disp: fix nasty bug which can clobber SOR0's clock setup
  drm/nvd9/therm: handle another kind of PWM fan
