Wouldn't it be nicer to have PCI use those dev_*() calls?

Another minor nit: addressing the various resource types. The platform bus code has multiple lookup schemes. Calls like resource_iomap() might be more flexible, so that lookup schemes can stay flexible. - Dave - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
