From: Jes Sorensen <Jes.Sorensen@xxxxxxxxxx> Hi, Working on a wifi driver I hit the case where ieee80211_determine_chantype() could end up accessing uninitialized stack data, if a driver advertised it's supported bands as having HT support, but only 20MHz channel support. This patch should take care of the issue by copying over *chandef into vht_chandef. I don't think it would be correct to set IEEE80211_STA_DISABLE_VHT here since I believe it is valid for a driver to support VHT without 40+MHz support? Please correct me if I am wrong. This is against the current staging tree, but should be valid for 3.18 and probably also the stable kernels.
