According to patch "drm/i915/aml: Introducing Amber Lake platform" (e364672477a1). Amber Lake uses the same gen graphics as Kaby Lake. And it is the member of KBL ULX series. So far, IS_KBL_ULX macro did not include AML platform. It may caused driver load DDI translation table for KBL H/S series for AML system. The change will lead driver to apply translation table for KBL Y for AML device to avoid unexpected eDP/DP signal quality issue.
