device_get_match_data() in ACPI case calls similar to acpi_match_device(). Hence there is no need to duplicate the call. Just assign what is in the id->driver_data.

We could just pass the "(const struct catpt_spec *)id->driver_data" in place of spec to catpt_dev_init() and we can get rid of the local temporary pointer?
If not, then I would cast out the spec before it's use: spec = (const struct catpt_spec *)id->driver_data; catpt_dev_init(cdev, dev, spec);
