Thanks for pointing!

Puuh ;-)

In what way is it broken? If we update to 4.1, will ubi work (mount
an existing UBI partition with fastmap) on existing boards?

What do you mean with "for the stable tree" ?

I am next week in Dublin on the ELCE so I have no time to look into
this issue ... maybe the week after ...

But you can try to update to 4.1 mainline linux (or maybe 4.2?)
I hope it is not too complicated ... I am sorry, I have no patches
prepared for this
