* iio_push_to_buffers_with_ts() - push data and timestamp to buffers

* @data: Pointer to sample data buffer.
* @data_total_len: The size of @data in bytes.
* @timestamp: Timestamp for the sample data.
*
* Pushes data to the IIO device's buffers. If timestamps are enabled for the
* device the function will store the supplied timestamp as the last element in
* the sample data buffer before pushing it to the device buffers. The sample
* data buffer needs to be large enough to hold the additional timestamp
* (usually the buffer should be at least indio->scan_bytes bytes large).
*
* Context: Any context.
* Return: 0 on success, a negative error code otherwise.
