The difference will be between CS5532 and CS5532 OLPC.

Looks like this comes from the failed message from the mfd_add_devices() above.

In most contexts '-1' doesn't really mean much to the casual observer. In almost all cases, it's better to use a human readable define. In this case PLATFORM_DEVID_* defines have already been provided for this purpose. While we're here, let's be specific about the 'MFD devices' which failed. It will help when trying to distinguish which of the 2 sets of sub-devices we actually failed to register.
