[PATCH net-next 0/4] netconsole: fix target enable race and configfs read locking

While looking into the sashiko report about local_ip_show() and
remote_ip_show() missing proper locking [1] (fixed in patch 3/4), I
noticed a couple other places that need locking: patch 1/4 fixes a
null-ptr-deref when enabling a target races against a NETDEV_UNREGISTER
event, and patch 2/4 fixes a use-after-free when the local_mac_show()
callback races against a NETDEV_UNREGISTER event. Patch 4/4 is mostly
cosmetic but worth fixing.
