Laurent reviewed the full series - thanks!
I went ahead and applied the patches for drivers where all
patches was reviewed.

I will send a v5 soon for tc358767 and nxp-ptn3460 where I have fixed
my brown paper bag bugs
.
I am very happy Laurent spotted these before we applied the patches.
This also gives a good indication of the quality of the review.
