[ Upstream commit bc84cff2c92ae5ccb2c37da73756e7174b1b430f ]
In some error handling paths, a call to 'iio_channel_get()' is not balanced by a corresponding call to 'iio_channel_release()'.
This can be achieved easily by using the devm_ variant of 'iio_channel_get()'.
This has the extra benefit to simplify the remove function.
