In struct bus_type, two linked lists are prepared for devices and drivers. The struct device represents two members, struct bus_type * bus and struct device_driver * driver. Similarly, the struct device_driver that represents the driver also has two members: struct bus_type * bus and struct list_head devices. The definition of struct device and struct device_driver is the same as that of struct bus_type in
