thanks for the hint.A quick grep of hid-custom* or custom* inside Documentation
/hid as well as drivers/iio/ doesn't yields anything related to hid custom
sensor driver.Manual search inside the folders recursively also give the same
result.I did this for kernel 3.18.x and 3.19.x.I inspired to find the
implementation of hid-custom sensor by looking at a code in google :?https://
github.com/pfps/yoga-laptop .My intention is to use the hid-custom driver to
retrieve the custom values inside the custom sensor fields .I built the above
module for custom sensor but got some failure in inserting the custom sensor
module - "?dmesg log "failed to setup attributes""?: so looking for an update
driver for hid-custom-sensor.I may be re-looking the same driver again if it
doesnt have an updated version.

Try asking about this on the linux-iio mailing list, the developers
there should be able to help you out much better than we can as they are
responsible for the existing hid iio drivers.

hope this helps,
