From: Mark Mentovai <mark(a)moxienet.com&gt; commit 09a02fdb919876c01e8f05960750a418b3f7fa48 upstream. Fixes 2.6.35.9 -> 2.6.35.11 regression: https://bugzilla.redhat.com/show_bug.cgi?id=671514 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. Signed-off-by: Mark Mentovai <mark(a)moxienet.com&gt; Cc: stable(a)kernel.org Acked-by: Luis R. Rodriguez <lrodriguez(a)atheros.com Signed-off-by: John W.
