Comment 6 for bug 1929895

Document provided by Intel:
https://www.kernel.org/doc/html/latest/hid/intel-ish-hid.html

Base on the document: the test steps will be:
1. Install tree:
sudo apt-get install tree
2. sudo tree -l /sys/bus/iio/devices/
3. Check if devices exited.

Example on AAEON's EHL board: https://certification.canonical.com/hardware/202109-29492/
u@linux:~$ sudo tree -l /sys/bus/iio/devices/
