Re: [PATCH] ALSA: pcm: Fix source frame count calculation

[Sreeraj S Kurup]

You're right. I checked the callback implementation, and 
"snd_pcm_plugin_client_channels()" always returns the input 
frame count. All plugins created through "snd_pcm_plugin_build()" 
use this callback.

So the condition "err != frames1" is not reached in the normal path. 
My patch is unnecessary. Sorry for the noise.
