[PATCH] PM: ARM: locomo: Drop suspend and resume bus type callbacks

From: Rafael J. Wysocki
Date: Tue Sep 26 2017 - 16:55:04 EST


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

None of the locomo drivers in the tree implements the suspend and
resume callbacks from struct locomo_driver, so drop them and drop
the corresponding callbacks from locomo_bus_type.
