[igt-dev] [PATCH i-g-t] tests/kms_force_connector_basic: Test Cleanup
Mohammed Thasleem

Tue Sep 27 19:31:28 UTC 2022
Sanitize the system state before starting the subtest.
v2: Created a new functions for each subtest instead
of managing the full logic within the igt_subtest().
v3: Minor changes.
v4: Replaced igt_assert_f with igt_require_f in prune-stale-modes.
