Please see commit c4f135d643823a86 ("workqueue: Wrap flush_workqueue()
using a macro") for background.
This is a blind conversion, and is only compile tested.

this approach means the driver will always allocate a workqueue even if
the associated hardware is never present.
did you consider instead having the allocation take place within the
processing of ath6kl_usb_probe() and the destroy take place within the
processing of ath6kl_usb_pm_remove()?
