Cannot silence lint `"warning: unnecessary lifetime parameter"`

[ritchie46]

Description

Due to macro's its sometimes not easy to adapt a warning.

This code creates the warning that the lifetime can be replaced directly:

pub fn foo<'a>(_s: &'a str) where 'a: 'static { }

warning: unnecessary lifetime parameter `'a`
 --> src/lib.rs:2:37
  |
2 | pub fn foo<'a>(_s: &'a str) where 'a: 'static { }
  |                                     ^^
  |
  = help: you can use the `'static` lifetime directly, in place of `'a`

However there does not seem to be a tag that allows us to silence it.

This is from rustc rust-lang/rust#96956

[ritchie46]

Yes, I backposted it here as I was not sure it belonged to clippy or rustc.

This is not a clippy issue, and the issue no longer reproduces since it was fixed in rust-lang/rust#108230, so this should be closed.
