From: Jean-Philippe Brucker <jean-philippe.bruc...@arm.com> Now that the infrastructure changes are in place, enable virtio-iommu to be built as a module. Remove the redundant pci_request_acs() call, since it's not exported but is already invoked during DMA setup.
Signed-off-by: Jean-Philippe Brucker <jean-philippe.bruc...@arm.com> --- This conflicts with the multiplatform work [1] since they both change Kconfig. Locally I have this patch applied on top of that series but there is no functional dependency between the two.
