| 4 | Subject: [PATCH 037/104] mtk: hostapd: Do not include HE capab IE if |
| 5 | associated sta's HE capab IE is invalid |
| 6 | |
| 7 | The parameter 'sta' passed to send_assoc_resp() might be NULL, so an |
| 8 | NULL check is necessary before access the 'sta'. |
| 9 | Only one such check was missed in this function, and this patch fixs it. |
