The errors on the APMT* identifiers are due to the missing ACPI patch, which was
submitted on different series: https://lkml.org/lkml/fancy/2022/4/19/1395.
Sudeep, could you please suggest if I need to combine ACPI and driver patches
into a single patch series ?

I will fix the warning on 'level' usage on the next version.

Regards,
Besar
