Series [v3,1/4] HID: hid-sensor-custom: Allow more custom iio sensors | expand

Commit Message

Philipp Jungkamp Nov. 17, 2022, 11:48 p.m. UTC
Use a generic 'hsdev->usage' instead of the HID_USAGE_SENSOR_PROX to
allow this driver to drive the Lenvo custom proximity sensor, which is
registered under a 'custom' usage and not HID_USAGE_SENSOR_PROX.

Add the Lenovo Intelligent Sensing Solution (LISS) human presence sensor
to the platform device ids.

Lines are shorter and the switch statement for raw_len is cleaner.

Didn't understand why this change is required.

Thanks,

Not sure if this is going via HID or IIO trees, so for now
