Patch looks good to me, though I'm not sure the Fixes: tag is useful. It
points to a commit that is 10 years old and the error message is
probably not worth backporting to every single actively maintained
stable release. I'm not sure it's worth backporting at all because it's
purely cosmetic.
That's up to Greg and Jiri, so from the Tegra side:
