Looks good for me:
Reviewed-by: Gregory CLEMENT <gregory.clement at free-electrons.com>
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
