Actually, you don't need to create a new PR. Just push to your previous branch, and then GitHub will update that PR.

@benjycui Sorry, I was being lazy and used the github editor to fix the linter errors. I could squash the changes on my other PR if you want.

And it's recommended to provide a re-producible online demo to show what you are going to fix, thanks.
