Is there really any great reason to use this as opposed to
module_platform_driver()?  I know the existing code does this, it's not
clear to me that that's a good idea either.

Since the init function returns platform_driver_probe() instead of
platform_driver_register(), I have used module_platform_driver_probe()
macro.

However, if your question is why return platform_driver_probe() at all
instead of platform_driver_register() in the first place, then I am
sorry I do not have much idea about it.

Yes, I'm questioning if this is the right cleanup to do.
