That won't quite work ... "at least one" includes "two" (i.e. a PCI card in little-endian, a native controller in big-endian). Real-world systems need such configs, or so I'm told, and that's why their supported. Is there maybe a way to force Kconfig to just reject such illegal configs -- neither option set -- rather than trying some how to fix it? Or maybe ... if neither one is set, have the header force both on, and issue a warning. -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
