It's not particularly related.

It's a 10 year old script that I just extended because it's
convenient for me.

I think I first posted it in 2011, but I started it as a
complement to checkpatch in 2010.

Doing the regexes for the fallthrough conversions took me
a couple hours.

I think clang-format could not do this sort of conversion.
Nor could coccinelle or checkpatch.

Anyway, it's not really necessary for this particular patch
to be applied, but it's a convenient way to show the script
has the capability to do fallthrough comment conversions.

I think it does conversions fairly reasonably but likely
some files could not compile without adding an #include
like:

#include <linux/compiler.h>
