Hi Arnd

You can simply this. DSA has never as far as i remember used an
interrupt passed via platform data. Two boards do seem to pass an
interrupt via a GPIO line, but it has never been used.

So if you want, you could strip all this interrupt code out.

There might be some patches coming soon which does add interrupt
support to DSA, but it will only be via device tree, since i don't
have a platform which is capable of using platform data for DSA.
