I've observed a NULL pointer dereference in ieee802154_del_iface() during netlink fuzzing. It's the ->wpan_phy dereference here: phy = dev->ieee802154_ptr->wpan_phy; My bet is that we're not checking that this is an IEEE802154 interface, so let's do what ieee802154_nl_get_dev() is doing. (Maybe we should even be calling this directly?)
