Sorry for the delay. I was having an internal deadline last week. I
just re-read the code, and I am quite happy with it. I also just
tested it on the i2c-hid w/ acpi machine I have here, and it seems OK.
So other than that, do we need to have approvals for patch 2/4
(arch/arm64/configs/defconfig)? I can easily take that in the HID
tree, but I prefer having the approval from the maintainers first.

If I can quickly get the approval from the arm64/config maintainers, I
can try to apply it. Though, I wouldn't be against you sending a clean
and conflict-free series :)

Heh. Sorry, I have a tendency to have my inbox flooded, and some time
gets distracted to do other important work I am paid for (too). I
don't mind a gentle nudge from time to time, that helps figuring out
the priorities :)
Cheers,
Benjamin
