mixed_attributes_style cannot be disabled globally

[apoelstra]

Summary

If the mixed_attributes_style lint is whitelisted in lib.rs/main.rs, but triggered in another file, it still triggers. The top-level whitelist appears to apply only to the top-level file, and inline modules within that file. Not modules which are different files.

Reproducer

I tried this code:

main.rs

#![allow(clippy::mixed_attributes_style)] // https://github.com/rust-lang/rust-clippy/issues/12435
mod submodule;
fn main() {}

submodule.rs

#[cfg(test)]
mod tests {
    //! Doccomment for my tests module
}

The lint triggers:

warning: item has both inner and outer attributes
 --> src/submodule.rs:1:1
  |
1 | / #[cfg(test)]
2 | | mod tests {
3 | |     //! Doccomment for my tests module
  | |______________________________________^

Is this similar to #6610?

Possible solution: #6610 (comment)

@tcharding seems like it, at the mean time I'll try moving this to LateLintPass to see if that fix it~
