As you might remember, my resource sharing work for snd-usb-audio and the shared media object API which is necessary for media driver and snd-usb-audio to share the media device are pending waiting for this RFC series to go from RFC to a version that can be merged. I would like to get the snd-usb-audio work done soon and target it for an upcoming release in the near future! Could you please send an update on the status on when the next RFC version might be sent out. thanks, -- Shuah
