Merge tag 'mac80211-next-for-davem-2017-02-09' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next

Johannes Berg says:

====================
Some more updates:
 * use shash in mac80211 crypto code where applicable
 * some documentation fixes
 * pass RSSI levels up in change notifications
 * remove unused rfkill-regulator
 * various other cleanups
====================
