`cargo fix` doesn't apply fixes it suggests

[xobs]

When running cargo fix (or any cargo command, really) it often ends with this message:

warning: `[package]` (bin "[binary]") generated 6 warnings (run `cargo fix --bin "[binary]"` to apply 5 suggestions)

However, doing so does not appear to actually apply any fixes. In fact, the above message came about as a result of running cargo fix.

I tried this code:

git clone --depth 1 --revision abbf996695d645b81a046b9451544a15a8bfeb27 https://github.com/probe-rs/probe-rs.git
cd probe-rs
cargo +nightly fix

I expected to see this happen: The lifetime warnings mentioned should be fixed

Instead, this happened: The repository is unchanged

May be considered fixed by #142980 but I will leave @shepmaster and others to be the judge

Thanks for the fast update, @workingjubilee !

[shepmaster]

No longer has the reported behavior.
