This should be a C++ comment with a SPDX header instead of the GPL
statement.

The driver is using snd_soc_codec quite a bit but we are trying to
transition away from that to snd_soc_component - you can see a lot of
example transitions in mainline from Moritmoto-san, everything that
exists at the CODEC level has a pretty direct equivalent in the
component struct so it's mostly (but not quite entirely unfortunately)
search and replace.

You should be able to add the controls that you're manually registering
in probe here.
