Subject: [PATCH 5.8 16/17] nl80211: fix NL80211_ATTR_HE_6GHZ_CAPABILITY usage

From: Johannes Berg <johannes.berg@...el.com>

commit fce2ff728f95b8894db14f51c9274dc56c37616f upstream.

In nl80211_set_station(), we check NL80211_ATTR_HE_6GHZ_CAPABILITY
and then use NL80211_ATTR_HE_CAPABILITY, which is clearly wrong.
Fix this to use NL80211_ATTR_HE_6GHZ_CAPABILITY as well.

Cc: stable@...r.kernel.org
Fixes: 43e64bf301fd ("cfg80211: handle 6 GHz capability of new station")
