`#[allow(clippy::enum_variant_names)]` not recognized when applied to individual variants

[pommicket]

Summary

The #[allow(clippy::enum_variant_names)] attribute is ignored when it's used on just an enum variant (it works fine if applied the whole enum).

Reproducer

I tried this code:

#[allow(dead_code)]
enum MyEnum {
    #[allow(clippy::enum_variant_names)]
    MyEnumIsGood,
    Yes,
    Hi,
}
fn main() {}

I expected to see this happen:

(No output from clippy)

Instead, this happened:

warning: variant name starts with the enum's name
 --> src/main.rs:4:5
  |
4 |     MyEnumIsGood,
  |     ^^^^^^^^^^^^
