Hi Stefan, Thanks for the patch. So this is why I couldn't build the driver between midnight and 2am here in France. :) Actually, I'd seen something about this on an old Microsoft blog, and had just forgotten whether there was a good solution. I'm glad you found it and sent this patch.
I can't apply this patch as-is because it's missing your Signed-off-by line. So you'll need to resubmit if you'd like it to be committed with your authorship. Otherwise I'll fall back to a Reported-by: line. Jason
