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
