Did you actually test this?
Also about the changes:

You can put them initializers except for private. Then the explicit memset can be omitted.

DRIVER_NAME, /* name */&portman_cb, /* callbacks */device_count); /* device number */
Does device_count really work similarly for parport_register_dev_model()? I supposed the argument being the device id number while you're passing the number of devices to create.
