Hello, I am not sure this is ready for sponsorship (I see it's In Progress), but I had a look at the debdiffs and I have some comments.

1. I see this is going to be a New package for Bionic/Focal/Jammy. Will this package in the future require backports of new upstream versions to stable releases because of compatibility reasons? (Note that I'm not familiar with the package!) If this is the case, you'll need a SRU exception [1], and I suggest using the same debhelper compat level for all the uploads, even those to newer releases. This will make reviewing easier.

2. In the upload manifests for stable releases (the .changes files), please include the full changelog of the packages, see dpkg-buildpackage -v (passed to dpkg-genchanges).

Hi Paride, thanks for having a look. I don't expect Bionic/Focal/Jammy to need backports for compatibility reasons, mostly because the latest changes were to enable compatibility with the 6.8 kernel. Only Jammy will need some form of compatibility with the 6.8 kernel as that will be the last HWE kernel for Jammy. Focal is still on 5.15 latest, and Bionic on 5.4. There may in the future be backports for particular features, but I wouldn't considered them compatibility related.

I can re-upload debdiffs with the full changelog - that makes sense.
