I've been looking at what code changes would be needed to fix this. I'm not convinced that there is enough reason to fix this unbind-rebind problem. There are risks in trying to fix it. I don't know of a reason why the driver needs to be unbound and rebound in normal operation. For debugging, the driver can be unloaded and reloaded to force a probe. I'd prefer only a documentation update to note that this error could be caused by unbinding and rebinding the driver without reprobing.
