linux-next: manual merge of the vfio tree with the drm tree

[Stephen Rothwell]

Hi all,

Today's linux-next merge of the vfio tree got a conflict in:

  drivers/vfio/pci/vfio_pci.c

between commits:

  b8779475869a ("vgaarb: provide a vga_client_unregister wrapper")
  f6b1772b2555 ("vgaarb: remove the unused irq_set_state argument to vga_client_register")
  bf44e8cecc03 ("vgaarb: don't pass a cookie to vga_client_register")

from the drm tree and commits:

  1cbd70fe3787 ("vfio/pci: Rename vfio_pci.c to vfio_pci_core.c")
  ff53edf6d6ab ("vfio/pci: Split the pci_driver code out of vfio_pci_core.c")

from the vfio tree.

I fixed it up (I reapplied the drm changes to vfio_pci_core.c - see below)
and can carry the fix as necessary. This is now fixed as far as linux-next
is concerned, but any non trivial conflicts should be mentioned to your
upstream maintainer when your tree is submitted for merging.  You may
also want to consider cooperating with the maintainer of the conflicting
tree to minimise any particularly complex conflicts.
