@vlimant thanks for opening the issue. #1821 change should now allow to run code-checks plus apply the changes.

When you open a PR for cmssw master branch then bot automatically run the code-checks. In case you want bot to automatically apply the code formatting changes then you can add code-checks and apply patch comment
