          Enable driver model for watchdog timer. At the moment the API
          is very simple and only supports four operations:
-         start, restart, stop and reset (expire immediately).
+         start, stop, reset and expire_now (expire immediately).
          What exactly happens when the timer expires is up to a particular
          device/driver.
