I've fixed the commit message (it's actually in the check for the *AP*,
not the driver!)
Also, this is complicated. We originally had the DISABLE_VHT, but then
found APs that were doing it wrong - see commit f3000e1b43f1 ("mac80211:
fix broken use of VHT/20Mhz with some APs"). That fix introduced the bug
here, going back now to the DISABLE_VHT as I'd suggested would break the
fix again ... I'm thus taking this version to just put the right data on
the stack, with the correct Fixes/Cc stable tags.
