Yes, I think I know what's going on. Platform devices call kfree() on
platform_data at release time. That's a little aspect of the API that
I had overlooked... suffice to say, I'd not set platform_data to
something that kfree() was expecting to see.
Best solution, probably, is to just set it to NULL prior to
unregistering the device. Will do something along those lines shortly.
Thanks,
jon
