   4 Subject: ath9k: support DT ieee80211-freq-limit property to limit channels
   5
   6 The common DT property can be used to limit the available channels
   7 but ath9k has to manually call wiphy_read_of_freq_limits().
   8
   9 I would have put this into ath9k_of_init(). But it didn't work there.
  10 The reason is that in ath9k_of_init() the channels and bands are not yet
  11 registered in the wiphy struct. So there isn't any channel to flag as
  12 disabled.
