Merge tag 'mac80211-for-john-2014-11-04' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211

Johannes Berg <johannes@sipsolutions.net> says:

"This contains another small set of fixes for 3.18, these are all
over the place and most of the bugs are old, one even dates back
to the original mac80211 we merged into the kernel."
