Sorry, my mistake. You are completely right and I don't know how I concluded
it was wrong. It's possible I got confused by the 'hwirq' string and thought
it could not refer to the resource, which is a virtual irq number rather than
a hwirq.
Anyway, I'll submit a new version with this fixup folded in:

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.

[PATCH] pinctrl: at91-pio4: use %pr format string for resource
resource_size_t may be defined as 32 or 64 bit depending on configuration,
so it cannot be printed using the normal format strings, as gcc correctly
warns:
pinctrl-at91-pio4.c: In function 'atmel_pinctrl_probe':
pinctrl-at91-pio4.c:1003:41: warning: format '%u' expects argument of type
'unsigned int', but argument 5 has type 'resource_size_t {aka long long
unsigned int}' [-Wformat=]
dev_dbg(dev, "bank %i: hwirq=%u\n", i, res->start);
This changes the format string to use the special "%pr" format
string that prints a resource, and changes the arguments so we
the resource structure directly. I'm also swapping out the arguments
to match the text in the format string.
