I think the problem was there always but 0-day builder did not hit it until recently: https://lore.kernel.org/lkml/202105082122.yrF7ploN-lkp@intel.com/ Best regards, Krzysztof

Anything to fix here? Best regards, Krzysztof

It was sent later, though. :( > Happens to me all the time. What is important is that things are getting fixed. Personally I don't care that much for the credit. Note though that your patch subject was a bit misleading, and it may well be possible that the mips maintainers didn't realize that the fix needed to be applied to the mips tree. The subject line in the applied patch describes the change much better as it focuses on the change (what is done), while the subject line in your patch focuses on the impact (what it fixes). Guenter
