> The individual iommu drivers report iommu faults by calling
> iommu_report_device_fault(), where a pre-registered device fault handler
> is called to route the fault to another fault handler installed on the
> corresponding iommu domain.
>=20
> The pre-registered device fault handler is static and won't be dynamic
> as the fault handler is eventually per iommu domain. Replace calling
> device fault handler with iommu_queue_iopf().
