The .conf files can be very easily compared with the original source.

Basically, I really want to let things to move forward. Everything is better 
than to have the topology configuration in the big repo with all other things, 
so I can accept this, too.

I had to probably use my time to work on something different than 
libatopology, but at least I found several problems and did a lot
of cleanups.

The packagers should ensure the version sync.

We are in trouble anyway :-) The new name is not much better (index inside
the control name not respecting the rules in control-names.rst - kernel 
documentation). But I know, someone missed to implement the control indexes in 
the whole ASoC tree ;-) SOC_SINGLE() etc... I'm talking about
snd_kcontrol_new->index.
