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

Pull drm fix from Dave Airlie:
 "Just a single fix for amdgpu to just suspend the gpu on 'shutdown'
  instead of shutting it down fully, as for some reason the hw was
  getting upset in some situations"

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
  drm/amdgpu: just suspend the hw on pci shutdown
