FYI: this is how the code looks now: + case WDIOC_SETOPTIONS: + if (get_user(new_value, p)) + return -EFAULT; + if (new_value == DA9052_ENABLE || new_value == DA9052_DISABLE) + da9052_sm_set_strobing_filter(wdt, new_value); + else + wdt->pwdt->sm_strobe_mode_flag = new_value; + return 0; Since the code is still not in line with the watchdog API and since I did not get an answer yet on what you (or Dajun) want to do, there is definitely NO ACK yet. If there is a good reasoning behind your needs, we might conclude that this is indeed worthwhile and extend the API in a proper way. But as it is now, it's not correct.
