Message-id: <4F62FDCE.8010609@renesas.com>
Date: Fri, 16 Mar 2012 17:46:06 +0900
From: "Shimoda, Yoshihiro" <yoshihiro.shimoda.uh@...esas.com>
To: netdev <netdev@...r.kernel.org>
Cc: SH-Linux <linux-sh@...r.kernel.org>
Subject: [PATCH 1/5] net: sh_eth: remove unnecessary function
The sh_eth_timer() called mod_timer() for itself.
So, this patch removes the function.
