Subject: [PATCH] netdev: don't allow register_netdev with blank name
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=88041b79f864dcd7f95e1d594eba683244dd968a;p=linux-beck.git

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

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().
