-Subject: [PATCH] cfg80211: move offchan_cac_event to a dedicated work
-
-In order to make cfg80211_offchan_cac_abort() (renamed from
-cfg80211_offchan_cac_event) callable in other contexts and
-without so much locking restrictions, make it trigger a new
-work instead of operating directly.
-
-Do some other renames while at it to clarify.
