In the future, it would be awesome if you could mention the tested-by
tag as mentioned here:
https://www.kernel.org/doc/html/v4.17/process/submitting-patches.html#using-reported-by-tested-by-reviewed-by-suggested-by-and-fixes

As the tree maintainer can then use it directly when merging the patch
in their tree.

So, for Jiri or Benjamin:

Tested-by: Peter F. Patel-Schneider <pfpschneider@gmail.com>

:)

Thanks for the testing, much appreciated!
