No, I'm not - I had heard about the Kconfirm project, but not about
this similar tool. Thanks for letting me know,

Yes, it does; it has orthogonal functionality to kconfig-sym-check,
which only operates within Kconfig files.
My script checks for CONFIG_* symbols that are referenced in code or
documentation, but that are not defined in any Kconfig file. The
decision to include documentation is intentional and has revealed
several instances of outdated documentation.
It also filters out symbols that are defined in a Makefile or
hardcoded with #define, and also attempts to filter out structs and
enums (and typedefs thereof) named CONFIG_*, though I need to improve
this further.
I will post it publicly once I have done so.
