I have browsed through the patch - and there was only a few things
that jumped at me.

With these points considered:
Acked-by: Sam Ravnborg <[email-masked]>

I expect only some (few) of my points to actually results in any updates.

I look forward to have the lint functionality as part of the built-in
tools so we catch these things early.

This change looks bad as it drops the alignment with the comments below.

The extra lines is a simple way to indicate that here shall be added
more in the future. So I like the empty line.

In the modern world we are living in now line length of 100 chars are
OK. checkpatch and coding_style is updated to reflected this.

Added one line too much?

Example is updated to use 4-space indent. I like.

But many other examples are left untouched.

So I wonder if updating all examples to the same indent should

Did you check that they are all in alphabetical order?
I would be suprised if this is the only issue in this file.
