Thanks a lot for the patch and the review.
I wanted to apply it but we have a regression upstream on the CI because
of an unrelated change in selftests:
https://gitlab.freedesktop.org/bentiss/hid/-/jobs/58744845
Once this is sorted out I'll apply the patch (or Jiri will). FWIW, b4
applies the Fixes tag all by itself, so I don't have extra steps to do
:)
Cheers,
Benjamin
