Better would be

	char buf[ENOUGH /* rofl */];

	pr_err("setting flow type for irq %u failed (%s)\n",
			irq, render_function_name(buf, chip->set_type));

However I'm presently brewing up a plot to do this:

	printk("function name is %Ss\n", (unsigned long *)chip->set_type);

which I think will work.  We can also do

	printk("IP address is %Si\n", (unsigned long *)ip_address_buffer);

to replace NIPQUAD.  And similar printk extensions.

Am still thinking about it though.
