[PATCH 1/2] iommu/s390: Fix IOMMU groups

From: Joerg Roedel Currently the s390 iommu driver allocates an iommu-group for every device that is added. But that is wrong, as there is only one dma-table per pci-root-bus. Make all devices behind one dma-table share one iommu-group. Signed-off-by: Joerg Roedel
