- * Prevent runtime suspend with a timeout after which runtime suspend would be

- * modified if the timeout is changed before timer fires.
- * If the timeout is less than autosuspend_delay then use mark_last_busy instead

- * It is wise to try not to use this API and correct the design if possible.
