Is there an explicit intent to deprecate Lindent in favor of checkpatch.pl
--fix? If one would like to contribute to fixing the tooling for linting which

Funny enough, this is something I adjusted manually :)

Ack. In fact, I was thinking this could be one target to fix the logic in

Thanks for the help and the review!
