Please just *stop* sending changes like this. See for example [1].

What's most offending to me is that I've replied to a lot of patches
from you, but I've *never* *even* *once* received a reply back on my
reviews.

If you want to participate in creating a better kernel, then please
*participate*. Just throwing random cleanup patches in our general
direction with one-way communication is not helping.

I'm seriously considering just ignoring *all* patches from you.


BR,
Jani.
