[PATCH] PCI: rpaphp: remove init error condition
The init function for the RPA PCI Hotplug driver returns -ENODEV in the case that no hotplug-capable slots are detected in the system. This is bad, since hot-capable slots can be added after boot to a purely virtual POWER partition. This is also bad because DLPAR I/O operations depend on the rpaphp module. Change the rpaphp init module to return success for the case of partitions that own no hotplug-capable slots at boot. Such slots can be dynamically added after boot.
