Hi Greg and Jiapeng,

First, IMO this is not research tool (in the sense of academic purposes),
but development bot used in corporate environment, kinda like kernel
test robot <lkp@xxxxxxxxx>. When the bot reports any build warnings,
these will be followed up by developers proposing fixes.

What I see in the patch message is just "Fix this warning..." without
saying why there is the warning.

Second, gcc DOESN'T, again DOESN'T, report "expecting prototype"
warnings. These are from scripts/kernel-doc, which enabled these
warnings on W=1 build.

So the underlying problem is mismatching function name in kernel-doc
comment and actual function.

Thanks.
