I cannot reproduce the same sparse errors.

Find a typo from my previous message. It should be "make ARCH=... C=1 ...".
2>&1 | grep -v sched | tee log.txt (Note: filter sched out to not get flood sparse errors) $ grep cros_ec_codec log.txt CHECK sound/soc/codecs/cros_ec_codec.c CC [M] sound/soc/codecs/cros_ec_codec.o
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?
Thanks. By using the version from github, it can generate the same sparse errors. $ sparse --version v0.6.1-rc1-43-g0ccb3b4
It seems current debian's version (i.e. 0.6.0 (Debian: 0.6.0-3)) cannot reproduce the errors even without the typo mentioned above.
Best Regards, Rong Chen
Guenter, what we could do in the case? Do you have any idea? _______________________________________________ kbuild-all mailing list -- kbuild-all@lists.01.org To unsubscribe send an email to kbuild-all-leave@lists.01.org
