There're couple of things the linter isn't happy about.

[newts]

I see. I will fix. can I run the lint on my own? it is just pylint?

There's a make command for that: https://github.com/KMKfw/kmk_firmware/blob/master/docs/en/contributing.md#code-style

[newts]

I ran black on my files and updated my master. I am not familiar with github pulls if there is more to do. I could not get the test to run on my system (ubuntu).
