Hi Rafael,
Basically, looks ok to me.
But it would be good if [v3 2/2] patch of this series (this patch) could be
applied in samsung tree to avoid conflicts as it modifies many files. I
don't want to make a trouble when sending my tree to upstream. Of course, as
you said, this have a dependency with [v2 1/2]. So if you're ok, let me
create topic branch will have both(1/2 and 2/2) to merge in your tree.
How do you think?
Thanks.
Best regards,
Kgene.
