cfg80211: Fix dfs state propagation for non-DFS center channel
When part of a bigger bandwidth (160 MHz) channel falls in DFS channel range it is possible that the center frequency may not necessarily be a radar channel. Remove the sanity check on channel flag for IEEE80211_CHAN_RADAR in regulatory_propagate_dfs_state(), this should fix the dfs state propagation for non-DFS center freq which has DFS channels in it's bandwidth, should also fix unnecessary WARN_ON() spam in regulatory_propagate_dfs_state(). Fixes: 8976672736d6 ("cfg80211: Share Channel DFS state across wiphys of same DFS domain") Reported-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Vasanthakumar Thiagarajan <vthiagar@qti.qualcomm.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
