The change will be in next via Thierry. I do not have to pull this in.

The maintainer which applies patches is responsible for:
1. Having his tree in linux-next,
2. Sending the patches to upstream maintainer (e.g. arm-soc, Linus)
later in pull request.

There is no job for me here, if I agree with Thierry. There would be a
job if I needed a separate stable branch, but that I did not decide
yet... Do you think I need to pull it? If so, why?

Best regards,
Krzysztof
