From 351f33d9e0d3e26adf0ef5180e1e28b4737c49ce Mon Sep 17 00:00:00 2001 From: Steve Glendinning Date: Wed, 28 Nov 2012 05:59:50 +0000 Subject: [PATCH] smsc75xx: 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.
