      - process all feedback from Dmitry except for threaded irqs; that'll have to be done later
Could I ask why? As it stands the remove() is racy WRT to a work
running. But if you simply add cancel_work_sync() you'll risk leaving
unbalanced enable_irq()/disable_irq().
ive never worked with threaded irq handlers before.  i'll have to read
about them before i can do the work.  i'm not suggesting you take the
driver now as is ... having it on a list in case someone else wants a
mostly-ok driver.
