[igt-dev] [PATCHv3 i-g-t] tests/kms_async_flips: Enable async flip on linear buffer

[Arun R Murthy]

On Intel Gen platforms >= GEN12, Async on linear buffer is supported,
hence enabling test for the same.

v2: Added new line character for igt_skip_on_f (Petri)
    Added new element modifier in data struct (JP)
v3: Use display ver instead of graphics ver(Jani N)
