[PATCH] workqueue: update kerneldoc
This patch (as812) changes the kerneldoc comments explaining the return values from queue_work(), queue_delayed_work(), and queue_delayed_work_on(). The updated comments explain more accurately the meaning of the return code and avoid suggesting that a 0 value means the routine was unsuccessful.
