I think this build failure is because mac80211_hwsim is an exception to
other wireless drivers and is applied via mac80211-next. Should we add
an entry for mac80211_hwsim to MAINTAINERS with the correct git tree? I
think kbuild test robot follows MAINTAINERS file nowdays (or at least I
understood that's the plan).

That's right. The robot parses MAINTAINERS when judging which tree
to apply LKML patches to.

Great. I'll add a commit to make mac80211_hwsim just part of the
MAC80211 entry.

Actually, come to think of it, why don't we do this in mac80211 rather
than the drivers?

The only capability it requires is inserting the IEs, and that's
handled in mac80211.

Well.. a driver may not want to advertise it... Moot...
I guess we can / should move it to mac80211.
