Actually, the original code is correct.
For boards with the Broadcom ID, this function checks that the boardrev is
sane. Dev boards that aren't properly configured may have invalid info, so this
check is mainly to catch that problem.
For boards with any other vendor, we don't have any sanity checks that we know
should be done, so the board info is always considered good.
The device ID is of course always checked.

Hi Henry,
Thanks for the explanation - I'm still a little confused on this...
probably more because of how the code reads. Let me explain:
The part that threw me off in this code when I originally read it is
that it always returns goodboard. It doesn't actually matter what the
vendor id is. So my first thought was "what did they really mean to code
here...?" That's why I sent the patch. So if the patch isn't necessary,
then great! :) But it seems like we could/should just drop the check for
vendor id?
thanks,
Greg
