3.8.13.11 -stable review patch. If anyone has any objections, please let me know. ------------------ From: Malcolm Priestley <tvboxspy@xxxxxxxxx> commit 5e8c3d3e41b0bf241e830a1ee0752405adecc050 upstream. Don't allow entry to iwctl_siwencodeext if device not open. This fixes a race condition where wpa supplicant/network manager enters the function when the device is already closed.
