| Subject: [PATCH] wifi: mac80211: only call drv_sta_rc_update for uploaded |
| stations |
| |
| When a station has not been uploaded yet, receiving SMPS or channel width |
| notification action frames can lead to rate_control_rate_update calling |
| drv_sta_rc_update with uninitialized driver private data. |
| Fix this by adding a missing check for sta->uploaded. |
