dio_match_device - Tell if a DIO device structure has a matching DIO device id structure : array of DIO device id structures to search in : the DIO device structure to match against

Used by a driver to check whether a DIO device present in the system is in its list of supported devices. Returns the matching dio_device_id structure or NULL if there is no match.

dio_register_driver - register a new DIO driver : the driver structure to register

Adds the driver structure to the list of registered drivers Returns zero or a negative error value.

dio_unregister_driver - unregister a DIO driver : the driver structure to unregister

Deletes the driver structure from the list of registered DIO drivers, gives it a chance to clean up by calling its remove() function for each device it was responsible for, and marks those devices as driverless.
