@roypat Seems like the failed "buildkite/kvm-ci/pr/clippy-riscv64" was a random CI failure?

yes, that looks spurious :)

[roypat]

seems like a few of the formatting changes already made it into this commit (e.g. also the import reformatting). :/

[phip1611]

i think it was the only one :)

[roypat]

Mh, seems like this one (and the import changes) are still in the first commit

[phip1611]

weird, sorry let me recheck. Perhaps I missed something when doing the rebase

[phip1611]

I think now its fixed :D

[phip1611]

I'll rebase this onto #337 before merging. Aye?

I dont think they conflict, so having this one going in first shouldn't be a problem :)
