Yes, your code is wrong, don't try to change the kernel core to work around it :)
That message is there for a reason, and this patch has been rejected many times in the past. kobjects can NOT ever be reused, and should never be static (but yes, there are lots of in-kernel users with static kobjects, they just never get reused...)
What code is emitting this message? I'll be glad to help you fix it up if you can point me at it.
thanks,
