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.
Rgds,

specific hid sensor drivers in drivers/iio/ for those specific chipsets
that are just a bit different from the specification.
Hope this helps,
