IMHO common API for disabling/enabling btcoex is something we would all
benefit from and easy enough to implement properly.  Burying it in
driver-specific debugfs is less than appropriate.

I seem to recall there were plans to discuss btcoex at one of the
linux-wireless summits.  If the consensus was to leave it in debugfs
then I apologize for the noise ;)
