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.
====================
