Changes in v2 RESEND:
- Add Daniel Lezcano to CC in the patch itself.
Changes in v2:
- Add Rob's Reviewed-by tag.

v1: https://lore.kernel.org/lkml/CAMhs-H_9kAdOfR-RaJWqAq6d3S3DXtKJqWy-EWCu0-ZjWKB9Sw@mail.gmail.com/T/#re9225265416ca8463c5f06d736f9834ae75efe0c

I am sending this with Rob's RB added since I ping for the v1 multiple
times without response. So I can be missing something or the patch is
lost for any reason. Thanks!
