Yes, please - even if we can only support a single watchdog at once it'd be helpful if the common code took care of that limitation and drivers mould be implemented with support for multiple watchdogs. It'll be less work when the core does get this support and until then it means that drivers don't need to worry about it. -- To unsubscribe from this list: send the line "unsubscribe linux-watchdog" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
