ChangeSet 1.1758, 2004/05/28 13:13:30-07:00, tpoynor@mvista.com [PATCH] Fix for leave-runtime-suspended-devices-off-at-system-resume.patch A patch to fix my previous leave-runtime-suspended-devices-off-at-system-resume patch; the new changes save a copy of power.power_state in order to know whether to resume a device, independently of mods to that field by a driver suspend routine. This fixes 2.6.7-rc1-mm1 in the same fashion as the updated 2.6.6 patch sent previously.
