I am building from the staging repository (gregkh/staging) and my
working branch when building is staging-next. So I am trying to build
from staging and not a particular version. I have also run `make modules_prepare`
and updated the .config per that script. However, when I do build
v6.1.0-rc1 from the main repository (torvalds/linux), I run into the same problem.
