SubjectRe: [PATCH] iio: accel: add missing sensor for some 2-in-1 based ultrabooks
Hi Hams,

https://github.com/systemd/systemd/pull/12322
https://github.com/hadess/iio-sensor-proxy/pull/262

As all the pull requests to systemd and iio-sensor-proxy has already
been merged, I just need your review on this:
https://github.com/systemd/systemd/pull/12449

Then, I guess this patch is ready to go. Please let me know if theres any issue.

Regards,
Luis
