This driver doesn't need any driver data/ platform_data beyond the 
i2c_id_table name (which has already been matched when probe()/ 
probe_new() is called), so strictly neither of_match_table nor 
apci_match_table would be necessary, because i2c DT/ ACPI enumeration also 
matches against i2c_table names.

But thanks for the hint ;-).
