From 81d37739dfded2ebd992f3bf8ae5d6cb1a0558cc Mon Sep 17 00:00:00 2001 From: Gerd Hoffmann Date: Thu, 23 Feb 2012 14:24:00 +0100 Subject: usb-ehci: fix reset Two reset fixes: * pick up s->usbcmd value after ehci_reset call to make sure it keeps the reset value and doesn't get rubbish filled in when val is written back to the mmio register array later on. * make sure the frame timer is zapped on reset.
