If you would like to fix it properly, then that's fine. The comment there says: /* FIXME: add defines for class 0x68000 and 0x80103 */ if ((dev->class >> 8) == PCI_CLASS_BRIDGE_HOST || dev->class == 0x68000 || dev->class == 0x80103) { The thing that's slightly confusing here is that dev->class contains the class in bits 24..8, but also the programming interface in bits 7..0. So, the comment is slightly wrong in that it's actually meaning class 0x0680 with a programming interface of 0x00, and a class of 0x0801 with a programming interface of 0x03. Your challenge is to _not_ add defines for these, but to use the existing defines for these classes, and modify the code to use those defines /without/ changing the effect of the checks. Ignore that there's no definitions of the programming interfaces - they can stay as raw numbers. -- FTTC broadband for 0.8mile line: currently at 9.5Mbps down 400kbps up according to speedtest.net.
