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

From: Joerg Roedel
Date: Tue Dec 11 2018 - 08:43:55 EST


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.



Joerg Roedel (6):
driver core: Introduce device_iommu_mapped() function
iommu/of: Use device_iommu_mapped()
ACPI/IORT: Use device_iommu_mapped()
powerpc/iommu: Use device_iommu_mapped()
xhci: Use device_iommu_mapped()
dmaengine: sh: rcar-dmac: Use device_iommu_mapped()
