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

Hi Greg,

Today's linux-next merge of the driver-core tree got a conflict in
drivers/iommu/tegra-smmu.c between commit a6870e928d1b ("iommu/tegra:
smmu: Support variable MMIO ranges/blocks") from the iommu tree and
commit bc5e6dea81b0 ("iommu: Convert to devm_ioremap_resource()") from
the driver-core tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).

Cheers,
