I think you should document the (locking) context here - you seem to
assume (later in mac80211) that this is only called in RCU critical
section, but I'm not really sure why? (IOW, I'm not sure that's even
correct?)

Also I suppose could use a note that this may be called within the
context of cfg80211_iter_combinations() so need to be careful about
locking with that, I think. I'm not sure it's *only* called in that
context?
