Just to confirm, you see this bug in v4.19-rc3, but not in v4.19-rc4?
There were only 3 iio specific commits added in v4.19-rc4, and none
stick out as being the fix, but it could have come from a non-iio
specific commit.

Title:
iio-sensor-proxy says: "Could not find any supported sensors" on Dell
XPS 15 9575 2-in-1 on Cosmic 18.10
Status in linux package in Ubuntu:
Triaged
Status in linux source package in Cosmic:
Triaged
Bug description:
On Cosmic, iio-sensor-proxy 2.4, with default 4.18 kernel as well as
latest mainline 4.19.0-041900rc3-generic.
There is no rotation lock button in the gnome-shell panel menu.
Gnome Settings > Device Display shows rotation buttons
There is no directory /sys/bus/iio
Reproduction:
1. Rotate device, fold display back to tent and tablet modes:
-> Rotation is not detected. When folding to tablet mode, device goes
to suspend as if display had been closed normally.
iio-sensor-proxy finds no sensors:
~$ systemctl status iio-sensor-proxy.service
● iio-sensor-proxy.service - IIO Sensor Proxy service
Loaded: loaded (/lib/systemd/system/iio-sensor-proxy.service; static; vendor
preset: enabled)
Active: inactive (dead)
I reported issue as https://github.com/hadess/iio-sensor-
proxy/issues/236 and was advised:
"Looks like there's no supported sensors, or just no sensors inside
this machine. Nothing that we can do about it, except asking your
vendor for support (eg. is there one or multiple sensors, and if so,
why aren't they supported in the kernel)"
I posted the issue in Dell's Project Sputnik's Google+ community
