Subject: wifi: cfg80211: handle IBSS in channel switch
From: Johannes Berg <johannes.berg@xxxxxxxxx>
commit 77e7b6ba78edf817bddfa97fadb15a971992b1ee upstream.
Prior to commit 7b0a0e3c3a88 ("wifi: cfg80211: do some
rework towards MLO link APIs") the interface type didn't
really matter here, but now we need to handle all of the
possible cases. Add IBSS ("ADHOC") and handle it.
Fixes: 7b0a0e3c3a88 ("wifi: cfg80211: do some rework towards MLO link APIs")
