An error snuck in between two recent conflicting changes: Until recently ->setup() used negative values to indicate normal test termination. This was changed in commit fa10366cc6f4 ("selftests/resctrl: Allow ->setup() to return errors") that transitioned ->setup() to use negative values to indicate errors and a new END_OF_TESTS to indicate normal termination.

commit 42e3b093eb7c ("selftests/resctrl: Fix set up schemata with 100% allocation on first run in MBM test") continued to use negative return to indicate normal test termination.

Fix mbm_setup() to use the new END_OF_TESTS to indicate error-free test termination.

Apologies, this error snuck in between the two series merged into kselftest's next this week.
