Heiko was not happy with this in PATCHv2, when he reviewed most
of the patches:

https://lore.kernel.org/all/3601039.e9J7NaK4W3@phil/

I replied, but never got a response, so I kept it as is:

https://lore.kernel.org/all/20221206170232.xsm4kcbfwrmlrriw@xxxxxxxxxxxxxxxxxxxxxx/

FWIW it is essential for the series and cannot be dropped, because
RK3588 has more than 2 channels.

Greetings,
