[FYI] cfg80211: HT40 fix for APs with odd country IEs for 2.6.33.y

[Luis R. Rodriguez]

Just a heads up to distribution maintainers, 2.6.33 has an
issue with disabling HT40 channels if you connect to an AP
that has an odd country IE. Specifically if your AP sends
out country IEs as follows:

[1-1]
[2-2]
[3-3]
[4-4]
[5-5]
[6-6]
[7-7]
[8-8]
[9-9]
[10-10]
[11-11]

instead of like this:

[1-11]

Then HT40 gets disabled. This issue was fixed on 2.6.34 and the fixes
were not propagated to 2.6.33.y as they are not "critical" fixes
per se, but if you do value this as "important" you may want to
fetch them and apply them to your 2.6.33.y kernel tree.

I've backported them and stashed them here:
