[PATCH v3 0/5] iommu: Implement generic_iommu_put_resv_regions()

From: Thierry Reding

From: Thierry Reding <treding@xxxxxxxxxx>

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 v3:
- add Reviewed-by from Jean-Philippe Brucker on virtio patch
- add Acked-by from Will Deacon on ARM SMMU patch
- rename to generic_iommu_put_resv_regions()

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