match_single_binding should ommit entire statement instead of suggestion broken "()" ?

Lint Name

match_single_binding

Reproducer

I tried this code:

pub fn a() -> usize {
    match 1 {
        _ => (),
    }
    2
}

pub fn main() {}

Clippy will suggest

pub fn a() -> usize {
    ()
    2
}

but this will not build

error: expected `;`, found `2`
 --> src/main.rs:2:4
  |
2 |     ()
  |       ^ help: add `;` here
3 |     2
  |     - unexpected token

maybe we can make it (); or just suggest removal of the entire match?
