This is not being used to pass ops, it is just a way to tell if an iommu driver was probed. These days this can be detected directly via device_iommu_mapped(). Call device_iommu_mapped() in the two places that need to check it and remove the iommu parameter everywhere.
Yes, that's much better than exposing the iommu ops to a place that should not care about them: Acked-by: Christoph Hellwig <hch@lst.de>
