I think we should use the following patch to remove the usage of
acpi_device_uid().  Crane, do you agree, or is there some special
reason you need it here?



i2c-scmi: don't use acpi_device_uid()
    
We recently removed the acpi_device_uid() interface because nobody
used it.  I don't think it's essential here either.
