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?

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

Do we need to revert those patches?

either that or fix it.
