Hi Benjamin

Thanks for the warning fixes.
This is legacy stuff that is not even wired into the kernel-doc stuff.
But that is no excuse for old-style comments.

Applied to drm-misc-next.

There is still quite a few of them in other drm files (drm_context.c,  
drm_bufs.c, drm_vm.c, drm_lock.c)

but I don't know how to fix them. Your advices are welcome.

I have no strong opinion on way forward here.
But if someone (you?) type the patches and they are even acked,
we should not ignore them.
