Subject: mac80211: avoid using uninitialized stack data
From: Jes Sorensen <Jes.Sorensen@xxxxxxxxxx>
commit 7e6225a1604d0c6aa4140289bf5761868ffc9c83 upstream.
Avoid a case where we would access uninitialized stack data if the AP
advertises HT support without 40MHz channel support.
Fixes: f3000e1b43f1 ("mac80211: fix broken use of VHT/20Mhz with some APs")
