The original mechanism for applying calibration assumed that the calibration data would be ordered the same as the amp instances. However, for some 4 amp laptops, this is not the case. To ensure that the correct calibration is applied to the correct amp, the calibration data contains a unique id, which matches a unique id inside the CS35L41. This can be used to match to the correct data entry. This mechanism is available inside the shared module cs-amp-lib.
