fix return value of snd_pcm_rewind()/snd_pcm_forward() to return how much actually has been rewound, instead of what actually could have rewound
PATCH 3/3 fix return value of snd_pcm_rewind()/snd_pcm_forward() to return how much actually has been rewound, instead of what actually could have rewound
Make snd_pcm_plugin_rewind()/_forward() actually return how much has been rewound/forwarded instead of how much could have been rewounded/forwarded. This makes the code actually do what the documentation of snd_pcm_rewind() suggests.
