amd-iommu: fix the handling of device aliases in the AMD IOMMU driver.
The devid parameter to set_dev_entry_from_acpi is the requester ID rather than the device ID since it is used to index the IOMMU device table. The handling of IVHD_DEV_ALIAS used to pass the device ID. This patch fixes it to pass the requester ID. [ Impact: fix setting the wrong req-id in acpi-table parsing ] Signed-off-by: Neil Turton <nturton@solarflare.com> Signed-off-by: Joerg Roedel <joerg.roedel@amd.com>
