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.
