  Hi all,

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

  drivers/iommu/iommufd/device.c

between commit:

  99f98a7c0d69 ("iommufd: IOMMUFD_DESTROY should not increase the refcount")

from the iommufd-fixes tree and commits:

  91a2e17e243f ("iommufd: Replace the hwpt->devices list with iommufd_group")
  d03f1336fd91 ("iommufd: Move putting a hwpt to a helper function")

from the iommufd tree.

I fixed it up (I used the latter version of this file and added the
following merge fix patch) 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.
