SPDX headers are supposed to be C++ comments, please send a followup

Another missing blank line.

This should really also support disabling TDM mode - if the parameters
are all 0 just turn TDM off. Again can be fixed in a followup.

You should add a Volume on the end of these control names so that
userspace knows how to display them properly; it's a little confusing as
they're not actually gains but it tends to work out better. Same for
most of the other TLV controls.
