Subject: [PATCH] cfg80211: remove CFG80211_MAX_NUM_DIFFERENT_CHANNELS
We no longer need to put any limits here, hardware will and
mac80211-hwsim can do whatever it likes. The reason we had
this was some accounting code (still mentioned in the comment)
but that code was deleted in commit c781944b71f8 ("cfg80211:
Remove unused cfg80211_can_use_iftype_chan()").
