Automatic merge from submit-queue
fixed the logging of which conversions.
Hi Guys,
After enable the function of logging of which conversions at [TestSpecificKind](d31a7cb301/pkg/api/serialization_test.go (L140)), I got the below errors:
```
pkg/api/serialization_test.go:140: cannot refer to unexported name api.scheme
pkg/api/serialization_test.go:140: undefined: api.scheme in api.scheme.Log
ok k8s.io/kubernetes/cmd/genutils 0.066s
```
So, this PR will fix that.
