Backport of NVIDIA#2212, scoped down to the cuda_bindings/tests/test_nvfatbin.py portion that applies to 12.9.x. The cuda_core/tests/test_utils.py portion of NVIDIA#2212 (the trailing-comma-in-parametrize-name fix) does not apply here because the 12.9.x version of that test file does not have the bug — its parametrize uses two names matching tuple values. What is fixed (verbatim from NVIDIA#2212): cuda_bindings/tests/test_nvfatbin.py had two tests using @pytest.mark.parametrize("arch", ["sm_80"], indirect=True) to override the fixture-level `arch` parametrization. pytest 9.1.0 now rejects this combination as "duplicate parametrization of 'arch'". Extract the CUBIN-building logic into a _build_cubin(arch) helper, drop the indirect override on the two tests, and call the helper inline with the hardcoded "sm_80" they need. Preserves intent (the override existed because target arch "75" must not match the CUBIN's arch). Closes NVIDIA#2226. Hunk body verified identical to the corresponding hunk in NVIDIA#2212 (commit a9156b6).
