dbg_macro not caught when in submodule

[vmalloc]

Lint name: dbg_macro

I tried this code:

// src/main.rs
#![deny(warnings)]
#![deny(clippy::dbg_macro)]

mod sub;

fn main() {
    sub::func();
}


// src/sub.rs
pub fn func() {
    dbg!(10);
}

I expected the dbg! macro to be caught when running cargo clippy.

Instead, the lint does not trigger, and clippy finishes successfully.

The surprising bit (perhaps connected to #4612 ?) is when running clippy after forcefully touching the file (e.g. find . -name "*.rs" -exec touch {}), clippy catches it just fine 🤷

I had the same problem with dbg_macro. (And maybe others.)
Even when using #![deny(clippy::all)] it did not report an error.
