rnfds is a guint, so in the following code from gstalsamixer.c, the error
condition will never get triggered.

  rnfds = snd_mixer_poll_descriptors (mixer->handle, pfds, nfds);
  g_assert (rnfds <= nfds);

  if (rnfds < 0) {
    GST_ELEMENT_ERROR (mixer, RESOURCE, READ, (NULL), ("alsa error: %s",
            snd_strerror (rnfds)));
