Thanks!

If the name can't be set, the following call to device_register() will
fail, and should be handled by the caller. Just like today when we
allocate the kobject name in device_register(). After the core has
switched over, the name allocation will only happen a few lines
earlier, it should not behave different otherwise. Is that what you
mean?

Thanks,
Kay
