I agree the format change but not swapping out the arguments. Why do you have the feeling they are not matching the text?
Few lines before you have: res = platform_get_resource(pdev, IORESOURCE_IRQ, i); atmel_pioctrl->irqs[i] = res->start;
Each bank has its own irq line this is what I want to print with hwirq. Of course it assumes that interrupts are declared in the right order.
