For now I'd rename it to arm_dma_iommu_detach_device() and only implement it in arm. Once I've got the dma mapping implementations consolidated to a small enough number we could think about something like a device quirk that tells the architecture to simply never even attach the iommu dma ops to start with. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
