    I'm not fine with the naming, as it really is doing more than
    registering a platform driver. But since I can not come up with a better name
    right now, I would really appreciate if you could add some comments there
    explaining what this routine (mfd_shared_platform_driver_register)
    does and in which cases it is needed. The OLPC example could also be
    mentioned.

    Cheers,
    Samuel.
