I guess moving it next to the other quirk may break the functionality of this quirk, cause the MBP 2018 one involves stuff regarding firmware revision as well. The original patch applies the quirk after the following lines of the code :- core_link_read_dpcd( link, DP_SINK_HW_REVISION_START, (uint8_t *)&dp_hw_fw_revision, sizeof(dp_hw_fw_revision)); link->dpcd_caps.sink_hw_revision = dp_hw_fw_revision.ieee_hw_rev; memmove( link->dpcd_caps.sink_fw_revision, dp_hw_fw_revision.ieee_fw_rev, sizeof(dp_hw_fw_revision.ieee_fw_rev)); Which seem to related to the firmware stuff. Moving it along with the 2017 quirk doesn't sound right to me, as this shall move the quirk BEFORE these lines of code instead. Maybe the author also knowingly added the quirk after these lines of code? As a workaround, could we move the 2017 quirk later, instead of moving the 2018 quirk before? This sounds more logical to me. Regards Aditya
