why not just remove it?

Will do

     case SkBitmap::kA8_Config:
       return 0;
     case SkBitmap::kIndex8_Config:
       return 8;
     case SkBitmap::kRGB_565_Config:
       return 16;
     case SkBitmap::kARGB_4444_Config:
       return 12;
     case SkBitmap::kARGB_8888_Config:
       return 24;
     default:
       NOTREACHED();
       return 0;
   }
