Also using only tabs, there is plenty of width to just indent the "[0] = { ..." with a tab too. Regards, Hans

There's also an extra space before the , consistently on the mV lines.

The SPI attached WM5102 codec on the Lenovo Yoga Tab 3 Pro YT3-X90F is not described in the ACPI tables. Add info to instantiate the SPI device for the codec manually.
