Yes, you are correct, and this is what we decided. But on a recent 
development, I was able to test this patch series with a HDMI 2.0 analyzer,
and when I tested the AVI IF (with VIC 97, 38x21 at 60 16:9) the analyzer 
was calling it legal, and was also able to detect the mode based on VIC.
So looks like its (fortunately) correct interpretation of the spec. But 
do you still think we should change it ?
