The driver has OF match table, still it uses ID lookup table for retrieving match data. Currently the driver is working on the assumption that a I2C device registered via OF will always match a legacy I2C device ID. The correct approach is to have an OF device ID table using of_device_match_data() if the devices are registered via OF.
