Most of client for this APIs are in other subsystem.
When I was working on the patch
[PATCH 2/2] thermal: generic-adc: Add ADC based thermal sensor driver

if I have devm_iio_channel_get() then I can get .remove callback at all.

I did not use this new APIs in my patch because they are in different 
subsystem.
