This patch (5/5) applies on top of:

https://lore.kernel.org/linux-acpi/20211210154050.3713-1-sbinding@opensource.cirrus.com/

Which still needs some work and which really should be merged
through the ACPI tree. IMHO it would be best to simply drop
this (5/5) from this series and move it to the v3 of the
series which I've linked to above.

1-4 can be merged through the alsa tree independently of 5/5 AFAIK.

Regards,

Hans
