When one registers an interrupt routine in the normal Linux kernel,
the request_irq function call carries a parameter ``dev_id'' that
identifies for which device the ISR has been registered. This
parameter is not available in the RTL request_irq. Does this mean that
one cannot share interrupts in real-time? Or is it a design option
to introduce the minimum amount of delay by just having one single ISR
to wake up? (And, as a consequence, if one has two devices on the same
interrupt, the ISR routine has to take care of the problem itself?)
