I'm not sure exactly what "warm fuzzies" you need, but currently:

* It has not had widespread testing. I could obviously test it on all 
machines I have here, something I should probably do anyway, but would 
that be enough for you?

* The upstream version of this patch, for Linux 3.2 (which is slightly 
different, this is a backported version) has received review from 
Stephen Warren at Nvidia, who has recently refactored the HDMI audio 
driver. He believes the patch looks good, but was unsure if he wanted 
more reformatting of the string at the same time.
