The "device name" and "device id" only makes sense if you share interrupts, which
I don't recommend, but ...
Implementing these for your handler using rtl_request_irq is quite straightforward,
however,
you might be better off using the new sigaction interface to interrupts since that
does nice
things like return the previous interrupt handler which makes sharing even more simple.
That is, you can just set up your signal handler to call the old signal handler when
it is
done.
Please ask more as we are working on making this interface more usable.
