Subject: wifi: cfg80211: Partial revert "wifi: cfg80211: Fix use after free for wext"
From: Hector Martin <marcan@xxxxxxxxx>
commit 79d1ed5ca7db67d48e870c979f0e0f6b0947944a upstream.
This reverts part of commit 015b8cc5e7c4 ("wifi: cfg80211: Fix use after
free for wext")
This commit broke WPA offload by unconditionally clearing the crypto
modes for non-WEP connections. Drop that part of the patch.
