From fbfb511548b686057e02f32ddf6e08a9e13206b8 Mon Sep 17 00:00:00 2001 From: Nobuhiro Iwamatsu Date: Fri, 1 Dec 2017 08:10:32 +0900 Subject: [PATCH] net: sh-eth: Change read/write() param to struct sh_eth_info This changes Change structure used in sh_eth_read and sh_eth_write function from struct sh_eth_dev to struct sh_eth_info. This is necessary to convert to Driver Model.
