AFAIK, this change is an error in the specs. I have since changed
it. Sorry I didn't catch it earlier.
Otherwise, this patch seems to be correct. All you need now are the
fixes for b43legacy_phy_initb5() and b43legacy_phy_initb6().

Ok, I've re-looked at the specs and made the appropriate
corrections. I've also gone through all of the PHY specs and found
one other correction. It's enclosed below for review.
Where do I go to find the stuff for ...initb5() and ...initb6()?
That one was also an error in the specs - fixed now.
On the V3 specifications site, click on the RecentChanges button and
select B5PHY and B6PHY to get the specs for the other routines. I
rechecked the specs, and all agree with my current (revised) routines.
