Subject: mac80211: TDLS: always downgrade invalid chandefs
From: Arik Nemtsov <arik@xxxxxxxxxx>
commit db8d99774c2682559b7648857697b9b588c6795a upstream.
Even if the current chandef width is equal to the station's max-BW, it
doesn't mean it's a valid width for TDLS. Make sure to always check
regulatory constraints in these cases.
