They have few users and a nasty surprise in terms of reentrancy guarantee as workqueue considers work items to be different if they don't have the same work function. Update rt2800usb.c to use INIT_WORK() instead of PREPARE_WORK(). As the work item isn't in active use during rt2800usb_probe_hw(), this doesn't cause any behavior difference. It would probably be best to route this with other related updates through the workqueue tree. Only compile tested.
