The thing is that I am not sure what happens to the platform data once probe() is done. Isn't it customary to mark it with __devinit and have it freed after probing is successful?
No, platform data should stay around forever. Otherwise, consider what would happen if your driver is built as a module and you unload and load it again.
__devinit can be discarded if you disable enough kernel features, HOTPLUG is the main one IIRC, modules might also need to go - drivers really ought to take a copy of platform data they plan to use at runtime, though practically speaking you have to try to trigger any problems.
