kunit: tool: undo type subscripts for subprocess.PopenWriting `subprocess.Popen[str]` requires python 3.9+.kunit.py has an assertion that the python version is 3.7+, so we shouldtry to stay backwards compatible.This conflicts a bit with commit 1da2e6220e11 ("kunit: tool: fixpre-existing `mypy --strict` errors and update run_checks.py"), sincemypy complains like so> kunit_kernel.py:95: error: Missing type parameters for generic type "Popen" [type-arg]Note: `mypy --strict --python-version 3.7` does not work.We could annotate each file with comments like `# mypy: disable-error-code="type-arg"but then we might still get nudged to break back-compat in other files.This patch adds a `mypy.ini` file since it seems like the only way todisable specific error codes for all our files.Note: run_checks.py doesn't need to specify `--config_file mypy.ini`,but I think being explicit is better, particularly since most kerneldevs won't be familiar with how mypy works.Fixes: 695e26030858 ("kunit: tool: add subscripts for type annotations where appropriate")Reported-by: SeongJae Park Link: https://lore.kernel.org/linux-kselftest/20230501171520.138753-1-sj@kernel.orgSigned-off-by: Daniel Latypov Tested-by: SeongJae Park Reviewed-by: David Gow Signed-off-by: Shuah Khan List of files: /linux-6.15/tools/testing/kunit/mypy.ini
