[PATCH 5/5 v1] PM / Domains: Do not restore all devices on power off error

From: Rafael J. Wysocki
Date: Wed Jul 06 2011 - 17:01:45 EST


From: Rafael J. Wysocki <rjw@xxxxxxx>

Since every device in a PM domain has its own need_restore
flag, which is set by __pm_genpd_save_device(), there's no need to
walk the domain's device list and restore all devices on an error
from one of the drivers' .runtime_suspend() callbacks.
