From 76b0fa91af8ca33cd68f52f2d02a05c488777f58 Mon Sep 17 00:00:00 2001
From: Ivo van Doorn <IvDoorn@gmail.com>
Date: Sat, 28 Mar 2009 20:32:07 +0100
Subject: [PATCH 3/9] rt2x00: Don't free register information on suspend
After suspend & resume the rt2x00 devices won't wakeup
anymore due to a broken register information setup.
The most important problem is the release of the EEPROM
buffer which is completely cleared and never read again
after the suspend.
