Subject: [PATCH 08/39] codecs: nvv4l2: support multiple L4T versions with
single build
Nvidia has the tendency to break compatibility on documented apis for no reason.
Adding new values to enums in-between older values and not the end is unacceptable.
A heuristic is now in use that can identify NvBuffer version and adjusts such values accordingly.
That depends on using nvv4l2_ext_utils header with the specific values there.
