See? I'm tired of this "how dare can you break my kernel!?" bullshit.
That's exactly the reason why I NACKed this patch.
I do _not_ understand the KConfig SELECT logic. And I do think almost
nobody does understand how that all works together.
In the past people came with similiar patches like yours that looked
obviously OK. They said sentences like "it is trivial to get the SELECT
logics right". But it turned out they were wrong and it introduced
other regressions that I was made responsible for.

SELECT is _extremely_ difficult to get right, as it completely ignores
dependencies. See all this FOOBAR_POSSIBLE select logic that we use
in SSB to get SELECT working correctly with dependencies.

So my solution for this particular breakage you are seeing here is
to wait for the bcm43xx removal, which will happen soon. That will
fix it and will have almost zero chance to introduce new bugs.

Blah. The people with a bcm4311 revision 1 wireless card plus a bcm44xx ethernet card.
You can count those people on two fingers.

Ok thanks. We'll see if it really was a simple fix then.
If it turns out to break something you will get mail. :)
You can send this patch to a netdev maintainer or the wireless maintainer.
Maybe one of those will sign it off. Good luck.
