In Apple Touch Bar, the contact ID is contained in fields with the HID_DG_TRANSDUCER_INDEX usage rather than HID_DG_CONTACTID, thus differing from the HID spec. Add a quirk for the same.
All these hid-multitouch patches were a part of appletbdrm driver upstreamed since kernel 6.15.
Due to 2 different trees, and some delay in review by hid maintainers, these got upstreamed in 6.17.
So, in case you wish to backport to stable, IMO, backport only till 6.15, which in practicality is just 6.16 as of today.
