Sadly, running Lindent on almost any existing source file in the tree will produce dozens of spurious diff hunks due to most other people manually formatting their code, so Lindent is quite useless in practice.
It really does bother me how much of the coders' and code reviewers' bandwidth in the kernel community is wasted due to these silly formatting issues. In most IDE-using communities these problems were solved a long time ago, by the IDE autoreformatting your code on commit, with no exceptions.
Linus shuns commits that do nothing by reformat code. However, if you go in and make a change, then you'll probably get marked down by the maintainer if you don't fix up the formatting at that time.
