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

Pull DRM fixes from Dave Airlie:
 "This is just a set of nouveau and radeon fixes, the nouveau ones fix
  some suspend/resume regressions since use of copy engines and some
  fixes for Z compression on some newer chipsets."

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
  drm/radeon/dce2: use 10khz units for audio dto calculation
  drm/radeon: Fix VRAM size calculation for VRAM >= 4GB
  drm/radeon: Remove superfluous variable
  drm/nouveau: ensure channels are stopped before saving fences for suspend
  drm/nv50/fifo: prevent races between clients updating playlists
  drm/nvc0/fifo: prevent CHAN_TABLE_ERROR:CHANNEL_PENDING on fifo fini
  drm/nvc0/fifo: prevent races between clients updating playlists
  drm/nve0/fifo: prevent races between clients updating playlists
  drm/nve0/ltcg: poke the partition count into yet another register
  drm/nvc0/ltcg: fix handling of disabled partitions
  drm/nvc0/ce: disable ce1 on a number of chipsets
  drm/nouveau/bios: fix thinko in ZM_MASK_ADD opcode
  drm/nouveau: fix build with nv50->nvc0
