Hi all,
Today's linux-next merge of the arm-soc tree got a conflict in
arch/arm/mm/dma-mapping.c between commit c2273a185354 ("ARM: 8288/1:
dma-mapping: don't detach devices without an IOMMU during teardown")
from the arm-current tree and commit eab8d6530cc0 ("arm: dma-mapping:
Set DMA IOMMU ops in arm_iommu_attach_device()") from the arm-soc tree.
I fixed it up (see below) and can carry the fix as necessary (no action
is required).
