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.

The next question is, how do we keep it W=1 clean going forward?

Most people don't use W=1 because it's too noisy, so it's a bit of a
catch-22.

In i915, we enable a lot of W=1 warnings using subdir-ccflags-y in our
Makefile. For CI/developer use we also enable kernel-doc warnings by
default.

Should we start enabling some of those warning flags in drm/Makefile to
to keep the entire subsystem warning free?

I think that's a good idea. At least the documentation fixes I just
merged could have been easily caught before submission.
