This is another simple conversion to device-managed functions, requiring the use of devm_iio_device_register() and moving the disabling of the device on a devm_add_action_or_reset() hook. The i2c_set_clientdata() can be removed, as the PM functions can work with just the device object, to obtain the i2c_client object.
