Subject: linux-next: manual merge of the driver-core tree with the iommu tree

Hi all,

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

  include/linux/iommu.h

between commit:

  f7f9c054a227a ("iommu: Remove iommu_group_get_by_id()")

from the iommu tree and commit:

  b18d0a0f92a8f ("iommu: make the pointer to struct bus_type constant")

from the driver-core tree.

I fixed it up (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.
