Dear all,
On the linux-next vanilla next-20240709 tree, I have attempted the seed KCONFIG_SEED=0xEE7AB52F
which was known from before to trigger various errors in compile and build process.
Though this might seem as contributing to channel noise, Linux refuses to build this config,
treating warnings as errors, using this build line:
$ time nice make W=1 -k -j 36 |& tee ../err-next-20230709-01a.log; date
As I know that the Chief Penguin doesn't like warnings, but I am also aware that there are plenty
left, there seems to be more tedious work ahead to make the compilers happy.
The compiler output is:
In file included from drivers/comedi/drivers/tests/ni_routes_test.c:22:

These are just unused variables, so to repeat I might be adding to the noise, but in certain configs they
prevent build success.
Hope this helps.
