Without these changes a negative error code returned by snd_pcm_avail_update() will be not handled correctly.

With this patch the returned error code of snd_pcm_avail_update() will be returned by snd_pcm_rate_avail_update().

Signed-off-by: Timo Wischer twischer@de.adit-jv.com --- Compared to v1[1] of this patch only the changelog and the subject has changed.
