Hi @Goffen we've set some links see in the CONTRIBUTING guide to see how sign your commits:

I'll change our CI/CD check so we pass clippy on the test target also.

@Goffen when I click on your commit I see a "Unverified" tag with this warning:

Hi @Goffen tell me if you struggle to sign your commit, I'll make the change in another PR

[Goffen]

Ah yes cant for the love of god sign stuff. Testing out with new commits aswell. I wanted to test out a solution to a problem I have in this repo and got annoyed about the warnings.
So yes, closing this PR and you can go ahead and fix in your.
Sorry for the trouble

@Goffen clippy warnings are fixed now and check in the CI/CD for all targets. Thanks for having raised the issue
