However, both of the helper function have slightly different prototype for the "match" argument. int (*) (struct device *dev, void *data) // bus_find_device vs int (*) (struct device *dev, const void *data) // class_find_device Unify the prototype by promoting the match function to use that of the class_find_device(). This will allow us to share the generic match helpers with class_find_device() users.
