Hi Linus!

Yes, it was a bit silly. Do not really know how that happened :-/

I guess I thought it was reasonable. But I should do as I have tried
to do in all other cases, the smallest possible change. And let you
check in code, if so, to capture what is missing.

New patch on the way!


Kind regards
Rickard Strandqvist
