From 7b9e75802f1c50bfeae53c86c0bfbc5c45fd8719 Mon Sep 17 00:00:00 2001 From: Steve Glendinning Date: Mon, 10 Dec 2012 01:03:08 +0000 Subject: [PATCH] smsc95xx: fix async register writes on big endian platforms This patch fixes a missing endian conversion which results in the interface failing to come up on BE platforms. It also removes an unnecessary pointer dereference from this function. Signed-off-by: Steve Glendinning Signed-off-by: David S.
