Because your ACPI table is missing the _DSD entries just like mine:
[ 6.111053] cs35l41-hda i2c-CSC3551:00-cs35l41-hda.0: error -EINVAL: Platform not supported -22
[ 6.111082] cs35l41-hda: probe of i2c-CSC3551:00-cs35l41-hda.0 failed with error -22

Looks like I had you grepping for the wrong thing. This is likely your issue as well if you want to share your dmesg.

<email address hidden> & <email address hidden>,
My suggestion for both of you is to follow up with Lenovo support as I mentioned and see where that gets us. If enough of us take issue, they might be inclined to fix it.

Failing that, if enough of us are affected, maybe we can start a petition?

I still haven't been able to follow up on my ticket. Too busy with work/life.
