Subject: [PATCH] netdev: don't allow register_netdev with blank name

From: Stephen Hemminger <[email-masked]>
Date: Fri, 17 Nov 2006 13:41:58 -0800

This bit of old backwards compatibility cruft can be removed in 2.6.20.
If there is still an device that calls register_netdev()
with a zero or blank name, it will get -EINVAL from register_netdevice().
