From 93160c6397e460bc4c7ac15323fb698f91ef02e5 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Mon, 9 Jul 2007 11:39:19 -0700 Subject: [PATCH] PM: do not use saved_state from struct dev_pm_info on ARM The saved_state member of 'struct dev_pm_info' that's going to be removed is used in arch/arm/common/locomo.c, arch/arm/common/sa1111.c and arch/arm/mach-sa1100/neponset.c. Change the code in there to use local variables for saving the state of devices during suspend. Signed-off-by: Rafael J.
