Thanks for pinging, I must agree the regression is out since quite a few
weeks. Despite having four Tested-by, this series was lacking Reviewed- and
Tested-by entirely.

Now Louis reviewed the whole series (thanks!), so my understanding of the
drm-misc policy is that I can apply the series, which I plan to do in a few
days to let anybody else comment.

Best regards,
Luca
