| Subject: [PATCH 037/104] mtk: hostapd: Do not include HE capab IE if |
| associated sta's HE capab IE is invalid |
| |
| The parameter 'sta' passed to send_assoc_resp() might be NULL, so an |
| NULL check is necessary before access the 'sta'. |
| Only one such check was missed in this function, and this patch fixs it. |
