In a scenario where vibra_enable is called and vibrator is running i.e. vibra_work is scheduled and vibra_timer. Suppose vibra_timer is started and has not expired yet. At this moment if vibra_work starts executing and acquires the vibra_lock and just before hrtimer_cancel is called, if old timer expires and timer callback starts executing then it will try to acquire vibra_lock and hence it will wait for vibra_lock, as it is already acquired by vibra_work. Now vibra_work->hrtimer_cancel will wait for timer callback to complete and timer callback will wait for vibra_lock to be free so that it can complete. This result in recursive waiting for vibra_lock and hence deadlock. As timer callback is running in interrupt context so above deadlock may trigger watchdog.
