title: warning: Not setting branch master as its own upstream
body: <p>I am trying to set git branch upstream but getting below warning.</p>
  <h3>Command</h3>
  <pre><code>git checkout master
  git branch --set-upstream-to master
  </code></pre>
  <blockquote>
  <p>warning: Not setting branch master as its own upstream.</p>
  </blockquote>
  <p>How can I solve it?</p>
  <p>Does that mean it already being tracing correct remote branch <code>master</code>?</p>
