cfg80211: introduce cfg80211_get_chan_state
Helper function for finding out which channel is used by a given interface. An exclusive channel can be used only by a single interface. This is mainly for non-fixed channel IBSS handling. Signed-off-by: Michal Kazior <michal.kazior@tieto.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
