SubjectRe: [PATCH v3 0/6] hid: Introduce device groups
From
Hi Henrik,

Thanks for handling this. I still won't have the time to review this
patch set before early may as I'm out of my office till then. Also
sorry for not answering the previous mails, I did not had a reliable
internet connection during my holidays.

Thanks,
Benjamin
