From: "Dr. David Alan Gilbert" <linux@xxxxxxxxxxx>
cfg80211_background_cac_abort() is unused.
It got renamed from cfg80211_offchan_cac_abort by commit
a95bfb876fa8 ("cfg80211: rename offchannel_chain structs to background_chain to avoid confusion with ETSI standard")
and that was originally added in commit
1507b1531981 ("cfg80211: move offchan_cac_event to a dedicated work")
but never used.
To me it looks like the queue is still used (I see a queue_work
in __cfg80211_radar_event), so I think it's just the wrapper that's
unused.
Remove cfg80211_background_cac_abort.
