Ah, so you can load it fine, but not safely unload it? In that case I think
it's better to leave it as tristate but remove the module_exit() function to
prevent unloading.

You'll have to change the module_platform_driver() back into a manual
module_init() function to register the driver, but that sounds like
the cleanest solution aside from fixing the notifier calls.
