So probably the card list is wrong against DC30.
I checked high resolution photo of DC30 on internet, and it confirms the fact that DC30 does not have adv7175.

Since DC30 and DC30+ are identical in the card list, perhaps it is a very old copy/paste error.

So I will add a patch removing adv7175 from DC30.

Thanks for the report
