Yes, I agree. The v6 series including resending 1/4 patch looks good to me.
But the patch V6 4/4 would be sent to upstream via samsung tree to avoid
useless merge conflicts and I think, it's possible.

So Rafael, please take 1/4 ~ 3/4 patches in your tree with my ack.

Acked-by: Kukjin Kim <kgene.kim at samsung.com>

If any problems, please let me know.

Thanks.
