It's included in five different structs: struct wlan_ie_ssid *ssid; But none of those *ssid pointers are used. So instead of doing this just delete the wlan_ie_ssid struct and delete every reference to it. Send that as a patch by itself and then repeat that process for the next struct. regards, dan carpenter
