[alsa-devel] [PATCH alsa-lib] pcm: rate: Don't return negative frame count on success in rewind

snd_pcm_rewind is documented to return <0 on failure and >=0 on success.

Signed-off-by: Andrew Eikum aeikum@codeweavers.com --- I checked all other rewind implementations, and this was the only one that obviously had this bug.
