[2.6 patch] drivers/net/arcnet/: possible cleanups

To: Andrew Morton <akpm@xxxxxxxx>
Subject: [2.6 patch] drivers/net/arcnet/: possible cleanups
From: Adrian Bunk <bunk@xxxxxxxxx>
Date: Mon, 2 May 2005 03:47:26 +0200
Cc: Jeff Garzik <jgarzik@xxxxxxxxx>, netdev@xxxxxxxxxxx, linux-kernel@xxxxxxxxxxxxxxx
Sender: netdev-bounce@xxxxxxxxxxx
User-agent: Mutt/1.5.9i
This patch contains the following possible cleanups:
- make needlessly global code static
- arcnet.c: remove the outdated VERSION
- arcnet.c: remove the unneeded EXPORT_SYMBOL(arc_proto_null)
- arcnet.c: remove the unneeded EXPORT_SYMBOL(arcnet_dump_packet)

Signed-off-by: Adrian Bunk <bunk@xxxxxxxxx>
