Hm it can be that I did something wrong but I simply followed advice seen 
in one of threads on lkml:

"
Dmitry: you cannot just "git pull" on linux-next, because each version of 
linux-next is independent of the next one. What you should do is basically

        # Set this up just once..
        git remote add linux-next git://git.kernel.org/pub/scm/linux/kernel/git/sfr/linux-next.git

and then after that, you keep on just doing

        git fetch linux-next
        git checkout linux-next/master
"

This is from today:

$ git fetch linux-next
