Well, those can be set to something better, it's just that ASoC defaults 
to DMI if there is no longname provided. So if you have any suggestions, 
we can do it while also changing card names.
But do note that it allows for differentiating between different 
machines using same card in case we need to do something custom for UCM 
on one of them:
2680 
access("/usr/share/alsa/ucm2/conf.d/avs_hdaudio/LENOVO-20KH006LPB-ThinkPadX1Carbon6th.conf", 
R_OK) = -1 ENOENT (No such file or directory)
2680  access("/usr/share/alsa/ucm2/conf.d/avs_hdaudio/avs_hdaudio.conf", 
R_OK) = -1 ENOENT (No such file or directory)
so while not pretty I'm not sure if we can do any better, without 
breaking above possibility. And in most cases UCM based on driver name 
should be enough, which looks pretty enough.
