The checks below use pr_info() in case the configuration is not valid.
Is this missing here on purpose?

I have tested it slightly and it seems to work (also on an older
kernel). I don't know if that qualifies it for a Tested-by but at least
Acked-by should do the trick:

Tested-by: Daniel Wagner <daniel.wagner@...-carit.de>
Acked-by: Daniel Wagner <daniel.wagner@...-carit.de>

cheers,
daniel
