Hi all,

Today's linux-next merge of the tip tree got a conflict in
drivers/iommu/dmar.c between commit bc2272dcecae ("iommu/vt-d: Clean up
log messages in intel-iommu.c") from the tree and commit 34742db8eaf9
("iommu/vt-d: Refine the interfaces to create IRQ for DMAR unit") from
the tip tree.

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