Subject[PATCH] PM: ARM: sa1111: Drop suspend and resume bus type callbacks
Date
From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

None of the sa1111 drivers in the tree implements the suspend and
resume callbacks from struct sa1111_driver, so drop them and drop
the corresponding callbacks from sa1111_bus_type.
