Why did you move the call to bus_remove_device() to be before the
platform_notify_remove() and notifier is called?
And I don't think this is really going to work well. You have created a
notifier for all devices in the system, right? How do you know what
type of struct device is being passed to your notifier callback? At
least with the platform callback, you knew it was a platform device :)

All driver core exports should be _GPL() please.
