It was reported by coccinelle, not robot, wasn't it?

I cannot find this report. This is an open source work and public
collaboration. The "Reported-by" usually means that the issue was
reported. Usually in public. Can we see the report?
Otherwise adding non-public reports is useless and clutters our
report-credit-system.
