thermal/drivers/qcom-spmi: Use devm_iio_channel_get
The iio_channel_get() function has now its devm_ version. Use it and remove all the rollback code for iio_channel_release() as well as the .remove ops. [Compiled tested only] Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Signed-off-by: Eduardo Valentin <edubezval@gmail.com>
