The driver core is pretty well > debugged. Just use "return platform_driver_register(...);" No, that's not helpful. The issue isn't the device probe code itself, the issue is things like module unload not doing what they're supposed to do and leaving the device lying around or something - there's rather more going on than just the plain API call.
