Acked-by: Christian König for this patch here.
I'm going to push patch #1 from this series into our internal branch
since that is actually a bug fix.
From my side the rest looks good as well, but going to leave this here
on the list until Shashank had time to take a look as well.
Thanks,
Christian.
