Subject: [PATCH v2 0/5] iommu: Implement iommu_put_resv_regions_simple()

From: Thierry Reding <treding@...dia.com>

Most IOMMU drivers only need to free the memory allocated for each
reserved region. Instead of open-coding the loop to do this in each
driver, extract the code into a common function that can be used by
all these drivers.

Changes in v2:
- change subject prefix to "iommu: virtio: " for virtio-iommu.c driver
