Hi Enric,

I have gotten around to reviewing this series, and hope to get
this in ASAP.

I found an issue with this commit, but I'll go ahead and fix it
myself as I'm creating the immutable branch. No need to respin the series.

By my diff, the above two lines were changed from the original CHROMIUM
commit, based on Doug's comment here: https://lkml.org/lkml/2017/2/22/630

However, this is an incomplete fix. Instead, we should pick this:
https://chromium-review.googlesource.com/#/c/444085/

I'll go ahead and do that. Thanks!

Benson
