[PATCH 3/7] ACPI / PM: Move runtime remote wakeup setup routine to device_pm.c

From: Rafael J. Wysocki
Date: Mon Oct 29 2012 - 05:11:34 EST


From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>

The ACPI function for setting up devices to do runtime remote
wakeup is now located in drivers/acpi/sleep.c, but
drivers/acpi/device_pm.c is a more logical place for it, so move it
there.

No functional changes should result from this modification.
