From: Wang Chen <wangchen@...fujitsu.com>
To: "David S. Miller" <davem@...emloft.net>,
NETDEV <netdev@...r.kernel.org>
Subject: [PATCH next]isdn: Kill directly reference of netdev->priv
Simply use netdev_priv() to replace netdev->priv.
When I was making this patch, I fixed some checkpatch warning.
But there are still some "line over 80 characters" warnings
not fixed.
Because if I fix such warning will change the code structure.
Dave if you don't like the checkpatch warning, please tell me.
