Can you please update this to make From: and Signed-off-by: match.


Also I don't know how you prepared this patch series, because this says
patch 4/4, but it's not part of the same series as the other patches.

I did pick up the first  3 patches, but then noticed that you are back
at using the original labels, so please see below and send all 4 patches
in a proper series.

As requested previously, can you please label this mdss_dp, to make it
sort nicely in the dts?

Thanks,
