Originally queue_delayed_work() used to negative error codes or 0 and 1
on success depending if the work was queued or not. It caused a lot of
bugs where people treated all non-zero returns as failures so we changed
it to return bool instead in d4283e937861 ('workqueue: make queueing
functions return bool'). Now it never returns failure.
Checking for negative values causes a static checker warning since it is
impossible based on the bool type.
