I don't know if this is the right way of solving this issue but this
error is now consistently thrown in kbuild compile-test reports w/
W=1.
Dear Pierre-Louis Bossart:
Thanks for your modifications. I have fixed the warnings in my latest
KGDB patchset and sent it out, but the merged KGDB patchset is not my
latest version.
I have sent a patch set to complement the missing ports, and I think
these warnings would disappear after this patch has been accepted and
merged.
Here is the patch to fix this warning:

Thank you Vincent, let's drop my hacky patch then.
