I’m a little confused here since this is my first time. Could you help me with it?
Is this what you're expecting : 
```
  func.func @vector_fma_2(%a: vector<24x2x2xf32>) {
    %0 = vector.fma %a, %a, %a : vector<24x2x2xf32>
    %1 = scf.execute_region -> vector<24x2x2xf32> {
        scf.yield %0 : vector<24x2x2xf32>
      }
    return 
  }
// CHECK-LABEL: func @vector_fma_2
//       CHECK: return 
```
