Documentation/SubmittingDrivers suggests these be implemented even when they do nothing. On the other hand, the platform code calls these functions 'legacy'. Suspend and resume operations should go into a pm_ops structure, pointed at by the driver's pm field. This approach would lead to a lot of boiler plate, while achieving nothing. Drop the functions instead.
