It was a bit difficult to find the warning among the thousand
I opened an issue against clang about it:
See https://github.com/ClangBuiltLinux/linux/issues/1379
but then found that this is already known. I think it would be best to
make the kernel test robot
set CONFIG_COMPILE_TEST to avoid issues like this. I have annotated a
number of symbols
that are known to cause unnecessary false positives in a similar way
to get a clean build.
