		Drivers match devices when i2c_client.driver_name and the driver name are
		the same; this approach is used in several other busses that don't have
		device typing support in the hardware. The driver and module name should
		match, so hotplug/coldplug mechanisms will modprobe the driver.
		The probe function is called when an entry in the id_table name field
		matches the device's name. It is passed the entry that was matched so
		the driver knows which one in the table matched.
