Merge branch 'for-airlied-next' of git://people.freedesktop.org/~mlankhorst/linux into drm-next

fixups for nouveau and fencing

* 'for-airlied-next' of git://people.freedesktop.org/~mlankhorst/linux:
  drm/nouveau: export reservation_object from dmabuf to ttm
  drm/ttm: add reservation_object as argument to ttm_bo_init
  drm: Pass dma-buf as argument to gem_prime_import_sg_table
  drm/nouveau: assign fence_chan->name correctly
  drm/nouveau: specify if interruptible wait is desired in nouveau_fence_sync
  drm/nouveau: bump driver patchlevel to 1.2.1
