Oh man, sorry about this (again). I did compile both drivers at the same
time, but only as modules and didn't realise the conflicts also with the
staging driver.

Yes, the cleaned up version of ath6kl is now in wireless-next and the
staging version can be removed in 3.2. Greg, how do you want to handle
removal of the staging version? Should I send a patch to you removing
it? Or should I send the patch to John?
