I see. It's definitely from the patch you sent though:

Yes, he overrides. I'd try to get away with just saying no though. That 
checkpatch thing desperately needs a clue.

Oh, missed commenting on this assignment-in-argument due to commenting 
on the other one...

Okay. Style-consistency really is fairly important. Otherwise you each 
time have to "retrain" while reading code. In that sense, even leaving 
them all in would/can be better than some in, some out although in this 
case "all out" is quite preffered.

(I only looked at the patch itself though -- if there are many more of 
these than leaving them in and (perhaps) fixing it in a follow-up might 
be preferred).

Thank you :-)
