As an extension of aef3156d7, there is no sense in repeatedly calling the 'wacom_set_report' and 'wacom_get_report' functions if they return an error. Getting an error from them implies that the device is out to lunch: either a hard error code was returned or repeated attempts at recovering from a "soft" error all failed. In either case, doing even more retries is not likely to resolve whatever is wrong.
