Unlike PCI hvapi, ATU hvapi registration failure is not hard error. Even if ATU hvapi registration fails (on system with ATU or without ATU) system continues with legacy IOMMU. So only log message when ATU hvapi successfully get registered. Signed-off-by: Tushar Dave <tushar.n.dave@xxxxxxxxxx> Signed-off-by: David S.
