That assumption only holds for certain devices on certain boards.
platform_device_probe() is a machine specific optimization that I will
not hesitate to remove if it breaks the driver on other machines.

More and more likely all the time though. Many drivers use the model
of registering child platform_devices (for instance, multi function
devices).
