I understand your worry. Tool is not prefect but it's useful to handle large amounts of code in
our first upstream, and helps us avoiding style mistakes.
While using the clang-format with the config in kernel tree, we also checked all the modifications
made by the tool carefully. We won't rely on tools too much with small changes in the future.
