[PATCH 0/6 v2] Introduce device_iommu_mapped() function

[Joerg Roedel <joro-zLv9SwRftAIdnm+yROfE0A@public.gmane.org>]

Hi,

here is the second version of this patch-set. It replaces
the various (dev->iommu_group) checks with a function call
which better expresses their intend.

Changes to the first version are the added patch for
rcar-dmac, a driver I missed before. I also added all
Acked-By's I received on the first version.

Please review and provide Acks, if there are no objections.
I have some iommu patches that depend on these, so I'd like
to carry this patch-set in the IOMMU tree.

Regards,

	Joerg
