Looks good for me:

Reviewed-by: Gregory CLEMENT <gregory.clement@xxxxxxxxxxxxxxxxxx>

I thinks this one should go to v4.12-rc as it is a fix.

As I modified the same part of the code in my series, I think I will
have to rebase my series on top of this patch as soon as Linus Walleij
will have accepted it.

Thanks,

Gregory
