This set is part of a larger effort attempting to clean-up W=1
kernel builds, which are currently overwhelmingly riddled with
niggly little warnings.

There are 5000 warnings to work through.

It will take a couple more sets.

I have a patch here that inline the comments - and fix the warning as a
side effect. I will get it posted tonight as this is better.

When I looked at his I had another unused function after removing the
first.

Agree on this simple approch, will apply.

OK, this was the one I referred to above. They should be squashed into
one patch.

As commented on the other patches, the subject prefixes on most of these
look wrong, but it's generally a nice cleanup.

Thanks!

The prefixes are automated.  I'll add this to my list of awkward
subsystems and go through them all manually again tomorrow. :D

I can squash them if you prefer.

tbh for autmoation they look really good :-)

I'd say if you replace the intermediate ": " with just a / you'll be
perfectly in style for drivers/gpu. But really I think it's ok as-is,
imo no need to change since this is a giantic tree wide effort.

Only the prefixes are automated unfortunately. :)

It's up to you.  Make the call and I'll abide.

Yes, you're not kidding, and thanks for noticing.

Only 10,000 (from 18,000) more to go though. :D

GPU is a biggy (5,000), although one patch in [Set 2] fixes 2,000 in
one hit, which is great!  I'll probably submit that tomorrow.
