From 3b14692c01e0b68f0ce51138dfcea967a63cd7bb Mon Sep 17 00:00:00 2001 From: Steve Glendinning Date: Fri, 30 Nov 2012 05:55:50 +0000 Subject: [PATCH] smsc95xx: don't enable remote wakeup directly As pointed out by Bjorn Mork, the generic "usb" driver sets this for us so no need to directly set it in this driver.
