Ideally, you would used MODULE_SYMBOL_PREFIX here, but of course it's a
string.  I don't think Kconfig can do arbitrary identifiers, so we can't
make CONFIG_SYMBOL_PREFIX empty or _.

Perhaps clarify it to a bool CONFIG_HAVE_MODULE_UNDERSCORE_PREFIX then,
since that's what you're assuming here?

Thanks,
