wifi: mac80211: mlme: Fix double unlock on assoc success handling
Commit 6911458dc428 ("wifi: mac80211: mlme: refactor assoc success
handling") moved the per-link setup out of ieee80211_assoc_success() into a
new function ieee80211_assoc_config_link() but missed to remove the unlock
of 'sta_mtx' in case of HE capability/operation missing on HE AP, which
leads to a double unlock:
ieee80211_assoc_success() {
...
ieee80211_assoc_config_link() {
...
if (!(link->u.mgd.conn_flags & IEEE80211_CONN_DISABLE_HE) &&
(!elems->he_cap || !elems->he_operation)) {
mutex_unlock(&sdata->local->sta_mtx);
...
}
...
}
...
mutex_unlock(&sdata->local->sta_mtx);
...
}
