I cannot reproduce the same sparse errors.

It did not generate the same message as 0day reported.
One difference would be the sparse version (it is from "apt install"
in my environment):
$ sparse --version
0.6.0 (Debian: 0.6.0-3)
On the other hand, 0day used "v0.6.1-rc1-42-g38eda53-dirty".
Hi,
The sparse warnings could be generated by the latest sparse
(https://github.com/lucvoo/sparse.git). Could you try again?
Best Regards,
Rong Chen
Guenter, what we could do in the case? Do you have any idea?
