Looks like it, yes. I'm using the 1.78 toolchain because it is
the oldest and we are supposed to verify that builds work with
the oldest:

<blueforge> linux-github (fix-clippy-double-parens-v2)$ clippy-driver --version
clippy 0.1.78 (9b00956 2024-04-29)

<blueforge> linux-github (fix-clippy-double-parens-v2)$ rustup which clippy-driver
/home/jhubbard/.rustup/toolchains/1.78.0-x86_64-unknown-linux-gnu/bin/clippy-driver

I'm not sure if this means we should workaround the problem or not.

thanks,
