Ooh, one more thing, and even if you insist on using HIGHPRI (please
don't), you don't need to create workqueue for each device. You can
just create one for the whole driver in init and destroy it from exit.
What matters is the HIGHPRI attribute of the workqueue. The number of
workqueues is completely irrelevant.
Thank you.
