  drm/nv50: prevent switching off SOR when in use for DVI-over-DP
  drm/nv50: fail auxch transaction if reply count not what we expect
  drm/nouveau: fix failure path if userspace specifies no valid memtypes
  drm/nouveau: report LVDS as disconnected if lid closed
  drm/nv50: prevent accidently turning off encoders we're actually using
  drm/nv50: fix alignment of per-channel fifo cache
  drm/nouveau: Evict buffers in VRAM before freeing sgdma
  drm/nouveau: Acknowledge DMA_VTX_PROTECTION PGRAPH interrupts
  drm/nouveau: fix thinko in nv04_instmem.c
