[PULL 24/42] hw/vfio: Remove memory_region_iommu_set_iova_ranges() call

Posted by Cédric Le Goater 5 months ago

From: Eric Auger <eric.auger@redhat.com>

As we have just removed the only implementation of
iommu_set_iova_ranges IOMMU MR callback in the virtio-iommu,
let's remove the call to the memory wrapper. Usable IOVA ranges
are now conveyed through the PCIIOMMUOps in VFIO-PCI.
