'Space expected around operator' picks up class name dash as operator

[seeliang]

I did a quick search for ' space-around-operator' could not find anything related to this.

Hope it is a real unique issue this time.

sass code

@mixin make-icon($name, $position: before, $prefix: null, $suffix: null) {
  $class: 'icon-#{$name}';
  @if $prefix != null {
    $class: #{$prefix}__#{$class};
  }

  @if $suffix != null {
    $class: #{$class}-#{$suffix}; // the sass lint error 
  }

  .#{$class} {
    @include add-icon($name, $position);
  }
}

• expect no error
• gulp sass 1.2.0
• with Atom editor
