I really don't mind, as long as it gets fixed.
The change is pretty obvious when you look at commit 69511a452e6dc.

There's one other fix required for the anx6345 and, while at it,
I had also fixed the code I copied in that hurry as well. 
What about these? All 3 fixes can go in independently, so I wouldn't
tie them to this series.
