Just noticed that, current krzk/for-next failed to boot on Exynos5880
based Chromebook device. Git bisect is showing culprit as this patch.
When I reverted this patch, its able to boot normally.
Is there any missing patches that we need to take on krzk/for-next to
boot on Chromebook.

Thanks,
Pankaj Dubey
