If kthread_park() returns an error, watchdog_park_threads() should not blindly 'roll back' the already parked threads to the unparked state. Instead leave it up to the callers to handle such errors appropriately in their context. For example, it is redundant to unpark the threads if the lockup detectors will soon be disabled by the callers anyway. Signed-off-by:
