Merge tag 'mac80211-for-davem-2017-11-20' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211

Johannes Berg says:

====================
A few things:
 * straggler timer conversions from Kees
 * memory leak fix in hwsim
 * fix some fallout from regdb changes if wireless is built-in
 * also free aggregation sessions in startup state when station
   goes away, to avoid crashing the timer
====================
