pci_common_init(&cats_pci); } It's the same number of lines. Otherwise, I think it's fine. I'll try to find some spare time to give it a go on a Netwinder. -- RMK's Patch system: https://www.armlinux.org.uk/developer/patches/ FTTP is here! 40Mbps down 10Mbps up. Decent connectivity at last! _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
