The iio_channel_release() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.

A much better change would be to use devm_iio_channel_get() instead of
iio_channel_get(), and to remove ntc_iio_channel_release() completely.
