The patch titled
PM: do not use saved_state from struct dev_pm_info on ARM
has been removed from the -mm tree. Its filename was

This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: PM: do not use saved_state from struct dev_pm_info on ARM
From: Rafael J. Wysocki <rjw@xxxxxxx>
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.
