Public bug reported: [Impact]
* Some Dell machine support ALS (ambient light sensor) will lost function after suspend/resume It originally only report iio-buffer-als by udev rule, but the buffer no longer update after suspend/resume, the issue can be eliminated by polling in_illuminance_raw node. [Test Plan] * Boot a machine with ALS support, and check it by $ cat /sys/bus/iio/devices/iio:device*/name => see if it contains name als * do suspend/stress by $ sudo -s # for i in `seq 20`; do sleep 5; rtcwake -m mem -s 10; done * run monitor-sensor and cover your hand on the light sensor $ monitor-sensor * if the als function lost, there should be no update of the ambient light sensor anymore [Where problems could occur] * The change add in_illuminance_raw check and add iio-poll-als IIO_SENSOR_PROXY_TYPE for it. * It will keep original IIO_SENSOR_PROXY_TYPE and multiple IIO_SENSOR_PROXY_TYPE support, so risk is low for other hardware.
