Subject: ath5k irq warning message

I'm working on debugging some sort of live-lock related to irqs
in ath5k with lots of virtual stations.

I notice this code in the ath5k_intr method.

Won't counter be -1 if you break out of this due to the 'counter-- > 0'
clause?

If so, then that warning won't be printed regardless...

	} while (ath5k_hw_is_intr_pending(ah) && counter-- > 0);

	if (unlikely(!counter))
		ATH5K_WARN(sc, "too many interrupts, giving up for now\n");

Thanks,
Ben
