The implementation is correct: - `vs_plane_reset()` properly frees any existing state, sets `plane->state = =3D NULL`, then allocates and calls `__drm_atomic_helper_plane_reset()`. - `vs_plane_duplicate_state()` uses `drm_WARN_ON` (device-aware) instead of= bare `WARN_ON`. - `vs_plane_destroy_state()` calls `__drm_atomic_helper_plane_destroy_state= ()` then `kfree()`. The `vs_plane_state` struct starts empty (just `base`) =E2=80=94 the `forma= t` field is added in patch 4. This is fine for bisectability. One note: `vs_plane_destroy_state()` does `kfree(state)` which frees the `d= rm_plane_state` pointer, not the `vs_plane_state` container. This works bec= ause `base` is the first member of `vs_plane_state`, so the addresses are i= dentical. This is standard kernel container_of pattern and is correct. --- Generated by Claude Code Patch Reviewer
