This patch description is not very good.

Just delete this comment.

Why move these to a seperate header file? That should have been
explained in the changelog. You forgot to include the header file.
Also you didn't compile this crap... :/

There are a lot of comments here that should just be deleted. For
example this one is worthless. If it were in kernel doc format then
it would be worthwhile, but as it is, you may as well just delete it.
All the commented out debug code should just be deleted as well. Maybe
send 2 patches. The first just deletes things and the second fixes up
style issues.

If you want you could just leave this as is. It's readable.
checkpatch.pl is there to serve you and not the other way
around.

^^^^^^^^^^
This should have been on the same line as TEST_UNIT_READY. But actually
it's a worthless comment. Delete if you want. Or leave it as it was as
I said before.

This is what I mean by debug code that should just be deleted.

Use KERN_DEBUG or pr_debug(). In the end, we'll have to delete these
before it gets moved out of staging. There was a similar issue in a
different change you made.
These are behavior changes and behavior changes should always be
mentioned in the changelod.

This is not the right way to do multi-line comments. Read CodingStyle.

DEBUG.
Etc.
