I'm using kernel 2.4.18, and I can see the code you posted. But this code doesn't help to find request_8xxirq. It just do the opposite. This code defines request_irq to be request_8xxirq when CONFIG_8xx is defined. But where is located the implementation of request_8xxirq?
Am I wrong? I didn't understand when that function request_irq is used. Thanks Tiago Alex Zeffertt wrote: >Maybe you're using a really old kernel.
