This would be normally the case for a patch which only fixes the

Sorry, but thanks for pointing out.

Reported-by: kbuild test robot

really hold? Because it suggests that the problem has been spotted by

added that for the minor compilation issue that you have fixed since the
last version.


Yes, I do know the issue is not reported by the robot, but
just followed the kbuild robot tip, this Reported-by suggested by kbuild robot

'If you fix the issue, kindly add following tag
Reported-by: kbuild test robot '

really hold? Because it suggests that the problem has been spotted by
the kbuild bot which is kinda unexpected... I suspect you have just
added that for the minor compilation issue that you have fixed since the
last version.
