Since commit d2e1a003af56 ("ACPI/IORT: Don't call iommu_ops->add_device directly"), we use the IOMMU core API to replace a direct invoke of the specified callback. The parameter @ops has therefore became unused. Let's drop it.

Sure, I will remove them in v2. Thanks for the reminder. Zenghui _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
