Well, right now if you change the ordering then the PCI interface will never be exposed. It would be preferable to only expose the ACPI interface as a user-visible device if there's no prior device - if there is, I think the ideal solution would be for it to be an in-kernel only device without a corresponding UI. -- Matthew Garrett | mjg59@xxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
