Drivers can add (e.g. in ->probe) attributes for devices using extern int device_create_file(struct device *device, struct device_attribute * entry); and delete them (e.g. in ->remove) using extern void device_remove_file(struct device * dev, struct device_attribute * attr);
and there's also
extern int driver_create_file(struct device_driver *, struct driver_attribute *); extern void driver_remove_file(struct device_driver *, struct driver_attribute *);
