I think it is, that was the original reason I wrote this patch. I'm writing some automated tests where I have to know what each stream is really connected to and the DAI name is important for that (in my case anyway). Since the PCM core already provides that in the info file it seemed reasonable to do the same for compressed.
In all the configurations we have with DPCM the name is snd-soc-dummy-dai, there is no connection to the codec proper. stream_name and id should be good enough, no?
There's going to be systems where the DAI name is something real and I can't see a disadvantage in providing that extra piece of information, just in case it's useful. I've kept the format the same as the equivalent for PCM
