tokio::select not compatible with clippy::default_numeric_fallback

Description
There might be good reasons for this, but the tokio::select macro is preventing me from activating clippy::default_numeric_fallback in my code.

pub async fn myfunc() {
    tokio::select! {
        _ = empty() => (),
        else => (),
    }
}

async fn empty() {}

Run with:

cargo clippy -- -W clippy::default_numeric_fallback

This is a bug of clippy that warns code generated by external macros.

Filed rust-lang/rust-clippy#7304 to report this bug, and filed #3831 to avoid this bug.
