This poses several problems: - Most structure members describe private core driver state, which should not be accessible by the child drivers, - The structure's lifetime is controlled by the child drivers, complicating use by the core driver. Fix this by moving the private core driver state to its own structure, managed by the RPC-IF core driver, and store it in the core driver's private data field. This requires absorbing the child's platform device, as that was stored in the driver's private data field before.

charset="utf-8" Now the rpcif_{en,dis}able_rpm() wrappers just take a pointer to a device structure, there is no point in keeping them. Remove them, and update the callers to call Runtime PM directly.
