That's the case in the PC world but obviously this is exactly how
essentially all embedded systems are built up.  It needs to be very
clear that this is just legacy code for these old PC sound cards and
nothing else, nothing about either the directory naming or the changelog
here suggests that this is anything other than the standard way to add
support for new CODECs to ALSA.

We usually have to go through a loop of "you need to use the frameworks"
with new vendors, we need to make the process of figuring out what they
should do as simple as we can.
