What I would like to point to is device_get_match_data() API which
should simplify / unify the case how you get driver data.

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 ;-).
