You don't need to overreact, he surely means only about the existing
ice1724 sound driver for his device :)

Restructuring ice1712 and ice1724 drivers to use ASoC would require
quite a lot of works, and no one really wants it, I guess.  Many
boards are old and can't be tested easily.  And, we still need to
match the ASoC components with the controls of the current driver.

This was already discussed a bit, and Clemens suggested like this
way.
