title: How to fix linter warning `Error return value is not checked`?
body: <p>I'm calling the method with error type value (foo() in code example). I don't care this result. What's the rigth code style way to write? Errcheck linter makes me check this error.   </p>
  
  <pre><code>//for example, same method may be called from imported entity
  func foo() error {
     if err := someFunction(); err != nil {
         return err
     }
     return nil
  }
  
  func process() {
     //linter doesn't like this
     foo()
  
     //this way leads to unused variable error
     err := foo()
  
     //is this clean way?
     _ = foo()
  
    return 
  }
  </code></pre>
