Re: [PATCH 0/2] mac80211: fix HT+ to HT- (and vice-versa) CSA

[Luca Coelho <luca@coelho.fi>]

(fixed Johannes' email address)

Both these bugs go far back, so IMHO they should go to 3.8 and stable.

1/2 goes back to 3.13
2/2 goes back to 2.6.30 (though the affected code changed somewhat
                         since then)
