[PATCH] pcm: set the snd_pcm_ioplug_status() tstamp field
Set the status tstamp field so that it can be accessed with snd_pcm_status_get_htstamp().

Is there a reason that the tstamp field of snd_pcm_ioplug_status() is always 0? I assumed that it was an oversight/bug so this patch sets it so that applications can read it with snd_pcm_status_get_htstamp(). I have tested it and it seems to work well. BR Jonas

I guess it's an oversight. It's one of few places where the no real hardware slave PCM is present, and the other one (null plugin) already set it. Also maybe cause snd_pcm_htimestamp() worked without this change; it's updating the timstamp with a different code path. In anyway, I applied your patch now. Thanks! Takashi
