Felipe,

I am seeing all sorts of deadlocks now, after removing the workqueue
(patch V2).  Some have easy fixes, but for others it is not as
obvious.  The code was much simpler when I could just trigger a
deferred worker function.

Workqueues are used in at91_udc, lpc32xx_udc, mv_udc_core, and
pch_udc.  Could you please clarify why it is not OK to use one in
bcm63xx_udc?

Thanks.
