Validated 

Below are the steps :

Nightly without fix :

[miyadav@miyadav debug]$ oc logs  machine-api-controllers-7fcbdc6dc9-2gqvn -c machineset-controller | grep "Registering Components"
2021/03/08 11:06:53 Registering Components.
2021/03/08 11:07:10 Registering Components.


Upgraded nightly to image which contains the fix 

[miyadav@miyadav debug]$ oc get pods
