            Bug ID: 218223
           Summary: Ambient light sensor on Framework 13 AMD laptop stops
                    working in Linux 6.7
           Product: Drivers
           Version: 2.5
          Hardware: AMD
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: IIO
          Assignee: drivers_iio@kernel-bugs.kernel.org
          Reporter: michael@michaelmarley.com
        Regression: No

The ambient light sensor on the Framework 13 worked properly with Linux 6.6. 
With 6.7 (currently tested with -rc4), the driver fails to load with:

hid_sensor_als HID-SENSOR-200041.1.auto: failed to setup attributes
hid_sensor_als: probe of HID-SENSOR-200041.1.auto failed with error -1

If I revert 286d528bf0fae9f334fba857825b9701df1675b2,
5f05285df691b1e82108eead7165feae238c95ef, and
ee3710f39f9d0ae5137a866138d005fe1ad18132, it starts working again.

This has also been reported in the Framework forums at
https://community.frame.work/t/tracking-auto-brightness-aka-ambient-light-sensor-in-linux-details/16746.

Patch to fix this issue

Please try the attached patch. I also posted upstream. This issue broke ALS on
almost all Intel systems.

AFAIU the commit f2a71ebdf231 ("iio: hid-sensor-als: Assign channels
dynamically") has to fix this. Correct me, if I'm wrong.
