Subject: [PATCH] via-velocity: Remove private device list

From: Ben Hutchings <[email-masked]>
Date: Sun, 25 Oct 2009 20:08:49 +0000

via-velocity maintains a list of its devices in order to determine
whether a netdev notification applies to one of them.  That can be
determined simply by checking the netdev_ops pointer, so the list can
be removed.

Compile-tested only.
