Merge tag 'mac80211-for-davem-2018-06-15' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211
Johannes Berg says:
====================
A handful of fixes:
* missing RCU grace period enforcement led to drivers freeing
data structures before; fix from Dedy Lansky.
* hwsim module init error paths were messed up; fixed it myself
after a report from Colin King (who had sent a partial patch)
* kernel-doc tag errors; fix from Luca Coelho
* initialize the on-stack sinfo data structure when getting
station information; fix from Sven Eckelmann
* TXQ state dumping is now done from init, and when TXQs aren't
initialized yet at that point, bad things happen, move the
initialization; fix from Toke Høiland-Jørgensen.
====================
