brcmsmac needs to hold cfg80211_mutex before calling freq_reg_info...

It looks like those calls were added in mid-June.

I think mid-june sounds about right. We never observed the warning when
changes to use regulatory infrastructure were tested/reviewed. Should
this precondition be mentioned in cfg80211.h?

Gr. AvS

Diving in further it seems brcmsmac can not grab the cfg80211_mutex. So
another solution is needed.

Yeah I was going to say -- how can it possibly access that? It seems
that in some patch the API got broken, it should be taking the lock or
whatever ... I'll leave it to Luis to sort out though :-P
