From: Alexey Khoroshilov <khoroshilov@xxxxxxxxx> This patch has been added to the 3.12 stable tree. If you have any objections, please let us know. =============== [ Upstream commit 8c2dd54485ccee7fc4086611e188478584758c8d ] In case of any failure ieee802154fake_probe() just calls unregister_netdev(). But it does not look safe to unregister netdevice before it was registered. The patch implements straightforward resource deallocation in case of failure in ieee802154fake_probe().
