Sorry for the confusion but the v2 is for OEM-5.14 only. This is for
5.15 Jammy and Unstable which can cherry-pick the whole set from linux
mainline cleanly. #4 patch "[PATCH 04/12][SRU][Jammy/Unstable]
drm/i915/tc: Add/use helpers to retrieve TypeC port properties" is
slightly different from the same patch in OEM-5.14.
