title: @SuppressWarnings("unused") gives warning: Redundant suppression after Android Studio update
body: <p>I have a private methods in some low level classes that are not currently in use, but I don't want the &quot;Method x is never used&quot; warning potentially obscuring other more important warnings. I added a standard warning suppression for that method:</p>
  <pre><code>    @SuppressWarnings(&quot;unused&quot;)
  </code></pre>
  <p>Up until recently that was working fine, no warning for that method. After upgrading to AS 4.1.1, however, these have started to get a &quot;Redundant suppression&quot; warning. If I remove the suppression the original unused warning comes back.</p>
  <p>I'm using Android Studio 4.1.1 (Nov. 4)</p>
