Hi Clément,

Thank you for keeping up the work on this series.

As the firewall header is moved to a dedicated firewall directory,
maybe it would be coherent to create the same kind of directory
for the sources as non-buses drivers use it. I can test it on my
side if you're willing to make the change.

Sorry for the late comment.

Cheers,
Gatien
