This patch creates a workaround for a bug in amd_iommu driver, where the driver doesn't save all necessary information when going to suspend. The workaround removes a device from the IOMMU device list on suspend and register a resumed device in the IOMMU device list.

Which bug do you workaround here? It needs to be fixed in the AMD IOMMU driver instead of being wrapped in KFD.
