From 5731858d0047cad309d334c4cd6ccb6199bf28fe Mon Sep 17 00:00:00 2001 From: Gertjan van Wingerde Date: Tue, 30 Mar 2010 23:50:23 +0200 Subject: rt2x00: Disable auto wakeup before waking up device. In all drivers ensure that auto wakeup is disabled before waking up the device. This is needed to prevent connection stability issues and problems in waking up the device.
