This is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID and that the MODALIAS reported will always be of the form i2c:. But this could change in the future so the correct approach is to have an OF device ID table if the devices are registered via OF. As pointed by Hans de Goede, there's no mssl1680 and this is just used in some ACPI systems to identify the gsl1680 chip. So isn't included in the OF device ID table since a DT should use the proper device name instead.
