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

Pull drm fixes from Dave Airlie:
 "I've been a bit slow gathering these:

   - drm/mst: one mutex leak in a fail path

   - radeon: two oops fixes, one dpm fix

   - i915: one messy set of fixes, where we revert the original fix, and
           pull back the proper set of fixes from -next on top.

   - nouveau: one fix for an illegal buffer placement.

  Doesn't look too bad, hopefully shouldn't be too much more"

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
  drm/nouveau/gem: return only valid domain when there's only one
  drm: fix mutex leak in drm_dp_get_mst_branch_device
  drm/amdgpu: add missing dpm check for KV dpm late init
  drm/amdgpu/dpm: don't add pwm attributes if DPM is disabled
  drm/radeon/dpm: don't add pwm attributes if DPM is disabled
  drm/i915: Add primary plane to mask if it's visible
  drm/i915: Move sprite/cursor plane disable to intel_sanitize_crtc()
  drm/i915: Assign hwmode after encoder state readout
  Revert "drm/i915: Add primary plane to mask if it's visible"
  drm/i915: Deny wrapping an userptr into a framebuffer
  drm/i915: Enable DPLL VGA mode before P1/P2 divider write
  drm/i915: Restore lost DPLL register write on gen2-4
  drm/i915: Flush pipecontrol post-sync writes
  drm/i915: Fix kerneldoc for i915_gem_shrink_all
