This should turn the incompletes into fails:

    drm/i915/selftests: Add a safety net to live_workarounds

    Since live_workarounds poke around the w/a registers and checks to see
    if they survive across a reset, we are prone to fouling the machine and
    leaving it in a non-recoverable state. Wrap the probe inside a timeout
    to abort the test if the reset fails.

    v2: Include GEM_TRACE on declaring wedged.
    v3: Add a few includes to make the header look standalone.
