This was previously part of the reverted locking rework, but it stands
alone just fine. It has already been in linux-next for a few weeks, this
folds the bug fix from:

https://lore.kernel.org/all/e5e75222-13a9-ee01-0c25-8311b622fe0d@samsung.com/

The patch "iommu: Add a lockdep assertion for remaining dev->iommu_group
reads" is pushed out of this series, even though the logic and explanation
behind that is still correct.

Jason Gunthorpe (7):
  iommu: Remove useless group refcounting
  iommu: Add generic_single_device_group()
  iommu/sun50i: Convert to generic_single_device_group()
  iommu/sprd: Convert to generic_single_device_group()
  iommu/rockchip: Convert to generic_single_device_group()
  iommu/ipmmu-vmsa: Convert to generic_single_device_group()
  iommu/omap: Convert to generic_single_device_group()

Applied on-top of the default-domain patch-set, thanks.

It caused some conflicts, but those were easy to resolve.

Thanks! I'll double check it
