Documentation and context is completely missing.

What does this driver have to do with Fintek chips ? We already have a driver
for those chips. Why would we want or need another driver for the same chips
under any circumstances ?

Also, new drivers shall use hwmon_device_register_with_info() to register
hwmon devices.
