From: Lior David <liord@xxxxxxxxxxxxxx> Move the call to wil6210_disconnect so it will be called before unregister_netdevice. This is because it calls netif_carrier_off which is forbidden to call on an unregistered net device. Calling netif_carrier_off can add a link watch event which might be handled after net device was freed, causing a kernel oops.
