Sorry I didn't see this patch sent yesterday:
https://lore.kernel.org/lkml/CAGOxZ50i6URzUQ7o7V4m7MR=2TqSeD6qx5fQaQDs+5nEq4fa2A@mail.gmail.com/

Looks like Krzysztof's patch covers my portion of the patch related to
EXYNOS_CHIPID. I'll keep an eye on his patch as it goes through and
will modify mine as needed since it's likely to come in after.

Thanks,
Will
