Allright. I'll merge it. It might have been nicer to write here

		phandle = list++;
		args = list;

		if (!*phandle)
			goto next;

		.../...

		list += *cells;

But it's not big deal, I'll merge it as-is and if you feel like it
you can aways submit a cleanup later. In fact you can even completely
drop "args" I think.

Cheers,
Ben.
