Hi Malahal,

I was wondering if you had any feedback (testing or otherwise) for these
patches:

https://patchwork.kernel.org/patch/384612/
https://patchwork.kernel.org/patch/384602/
https://patchwork.kernel.org/patch/390882/

We haven't heard from Hannes in a bit but I was hoping we could at least
understand that the few changes I made are agreeable and working as
expected.

Thanks,
Mike
