Damn it, you're right. My sincere appologies.
As the Documentation got fixed nicely I assumed my patch is good.
But of course a c file is more sensitive to tab/spaces!

Now it applied like charme on the debian 3.9.6 kernel source :

/mnt/tmp/src/linux-3.9.6 % cat

I am compiling now and I'll let you know!
