From foo@baz Mon Oct 7 18:11:58 PDT 2013

To: Greg KH <gregkh@linuxfoundation.org>
From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Subject: virtio: convert bus code to use dev_groups
The dev_attrs field of struct bus_type is going away soon, dev_groups
should be used instead. This converts the virtio bus code to use the
correct field.
