3.2-stable review patch. If anyone has any objections, please let me know.
------------------ From: Daniel Mack <zon...@gmail.com> commit 4d7b86c98e445b075c2c4c3757eb6d3d6efbe72e upstream. In check_input_term() and parse_audio_feature_unit(), propagate the error value that has been returned by a failing function instead of -EINVAL. That helps cleaning up the error pathes in the mixer.
