Arnd, Olof, Kevin,
This patch is a fix concerning material that had been added to 4.1, so
it's not exactly a regression.
So, as we missed the last train to 4.1, I'd like to queue it for 4.2 but
it's the only patch I have on top of my previous DT pull-request
(at91-dt4, not taken by you, yet).
So, should I build another pull-request (at91-dt5) or can you take this
single patch when you pull the at91-dt4 material?
BTW, here is the link to patchwork if it's easier:

Thanks, bye,
