The checker is automated, but it also produces false positives for
certain kinds of bugs/defects, so we decided to run the bot on our
servers at the University of Erlangen-Nuremberg. It runs daily on
linux-next; we check the reports and fix the issue as above or we
report it to the authors and maintainers. So we catch things as soon
as they are in linux-next.
If you want to check for symbolic issues (i.e., references on
undefined Kconfig opionts/symbols) you can use
scripts/checkkconfigsymbols.py which detects most of the cases.
However, this script did not catch the upper case (I will check why).
Kind regards,
Valentin
