Hi all,

After merging the drm tree, today's linux-next build (x86_64
allmodconfig) failed like this:

/tmp/next/build/drivers/infiniband/core/umem_dmabuf.c:210:10: error: 'struct dma_buf_attach_ops' has no member named 'move_notify'
  210 |         .move_notify = ib_umem_dmabuf_revoke_locked,
      |          ^~~~~~~~~~~

Caused by commit

  932f1eef09ecb (RDMA/umem: Add pinned revocable dmabuf import interface)

from the rdma tree interacting with commit

  ef246da8e63c4 (dma-buf: Rename .move_notify() callback to a clearer identifier)

from the drm tree.  I have fixed this up as below and can carry as
required.
