Subject: wifi: cfg80211: remove chandef check in cfg80211_cac_event()
From: Johannes Berg <johannes.berg@xxxxxxxxx>
commit d6f671c8a339d5b655acfacb8be6918c744fbabf upstream.
The current check only worked for AP mode, but we can do
radar detection in mesh as well (for example). We could
try to check this using wdev_chandef(), but we also don't
really care since the chandef is passed in and we have no
need to use it anymore (since we added the argument in
commit d2859df5e7f0 ("cfg80211/mac80211: DFS setup chandef
for cac event")).
