Subject: cfg80211: fix can_beacon_sec_chan, reenable HT40
X-Git-Url: https://bbs.cooldavid.org/git/?p=net-next-2.6.git;a=commitdiff_plain;h=09a02fdb919876c01e8f05960750a418b3f7fa48

cfg80211: fix can_beacon_sec_chan, reenable HT40

This follows wireless-testing 9236d838c920e90708570d9bbd7bb82d30a38130
("cfg80211: fix extension channel checks to initiate communication") and
fixes accidental case fall-through. Without this fix, HT40 is entirely
blocked.
