Hehe :)

But I don't see why this patch 5 should go either to mac80211 or
wireless-drivers trees as there's no dependency or anything like that,
AFAIK it's just cleanup. So it would simplest to get this patch 5 to
staging tree, less conflicts that way.

Patches 1 and 2 of course go to mac80211 tree and patch 4 goes to
wireless-drivers.
