+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.
