[PATCH] D52135: [Clang-Tidy: modernize] Fix for modernize-redundant-void-arg: complains about variable cast to void

[Idriss via Phabricator via cfe-commits]

IdrissRio updated this revision to Diff 165741.
IdrissRio added a comment.

Thank you @JonasToth. As you suggest I have added the test for the 
templatic function.
