Thank you for your work. I've sponsored libmbim. libqmi looks weird, your stack of backported changes include 0001 -release-bump-version-to-1.14.0.patch, if we are actually updating to the new version it would make sense to take the corresponding tarball and have the debian/changelog reflecting the actual version. Did you cherry pick specific changes or basically backported all changes between the versions? If so why not just taking the new tarball?
