Hi all,

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

drivers/xen/gntdev-dmabuf.c:360:12: error: initialization from incompatible pointer type [-Werror=incompatible-pointer-types]
  .attach = dmabuf_exp_ops_attach,
            ^~~~~~~~~~~~~~~~~~~~~

Caused by commit

  a240d6e42e28 ("xen/gntdev: Implement dma-buf export functionality")

interacting with commit

  a19741e5e5a9 ("dma_buf: remove device parameter from attach callback v2")

from the drm tree.

I have added the following merge fix patch:
