my view on this is that you're hunting the false problem here. I
wonder how likely it is that two hardwired WL12xx chips are there on
the same board.

It's theoretically possible that there's one hardwired device and one
hot-pluggable one but the latter one can't have platform_data anyway.

So in my opinion, we either should keep things simple and consider 2
hardwired WL12XX's to be a very very unlikely case, or we'll end up
discussing board_info once again.

Thanks,
   Vitaly
