Of course, I take that this check `anyRankedTensor` guards against scalar-only eltwise op as linalg requires a shaped type for its types. It'd be great to have a one test case that covers this scenario and ensures that the pattern doesn't match (and nothing blows up 😉).

You could add sth like this:
```mlir
@func negative_scalar_only_eltwise(...) {
// CHECK-NOT: linalg
arith.addf ... : f32
```
