Nice work, I'll go queue this up. I doubt > anyone will notice as this is a very old driver :) > Yep; by the way, notice the link to the Kernel CI test results: https://github.com/GustavoARSilva/linux-hardening/blob/master/cii/kernel-ci/hpilo-20200714.md I plan to add the generation --and inclusion in the changelog text-- of such links to my workflow, whenever possible. When Kernel CI reports 'SUCCESS', they don't send the report to any mailing list; they only send those reports to the maintainers/developers. So. I'm going to store the ones I get in this github repository: https://github.com/GustavoARSilva/linux-hardening/tree/master/cii/kernel-ci/ Thanks -- Gustavo
