Not right setup contrast for driver u8g_dev_ssd1309_128x64_fn

File "u8g_dev_ssd1309_128x64.c"

uint8_t u8g_dev_ssd1309_128x64_fn(u8g_t *u8g, u8g_dev_t *dev, uint8_t msg, void 
*arg)
{
...
    case U8G_DEV_MSG_CONTRAST:
      u8g_SetChipSelect(u8g, dev, 1);
      u8g_SetAddress(u8g, dev, 0);          /* instruction mode */
      u8g_WriteByte(u8g, dev, 0x081);
>>>>> u8g_WriteByte(u8g, dev, (*(uint8_t *)arg) >> 2);
      u8g_SetChipSelect(u8g, dev, 0);      
      return 1; 
...
}

u8g_WriteByte(u8g, dev, (*(uint8_t *)arg) >> 2) - not right,

must be

u8g_WriteByte(u8g, dev, (*(uint8_t *)arg));
