Alexandre, if Gerd does not reply in a week or so, then please add "S: Orphan" 
to MAINTAINERS for now to make it clear that there is no maintainer for sndio 
yet to increase the chance for somebody to adopt it.

From Volker's response I assume you will be posting a v3 anyway.

If nobody takes care to queue your patch then let me know. Maybe I can push it 
through my queue this time, provided that there are enough reviews. I also saw 
your patch just by coincidence BTW, so please CC maintainers of affected files 
as suggested by Volker.

Best regards,
