Incremental fix means V4 or additional patches?

i not quite sure i follow you, this IEC control is not already standard?
Userland applications like Gstreamer seem already use it...
The only limitation i saw is that i did not succeed in associated 
control to PCM device, only to CPU DAI. As i will have one additional 
IEC control for HDMI, i will need to manage control index, aligned to 
CPU DAI index, but not to PCM device index.
