             : 	while (retry-- > 0) {
             : 		if (realtek_mst_i2c_spi_in_isp_mode(fd) == 1)
             : 			break;
             : 		struct timespec wait_200ms = { 0, (unsigned)2e8 };
             : 		nanosleep(&wait_200ms, NULL);
             : 	}

             : 	if (retry < 0)
             : 		return SPI_GENERIC_ERROR;
I think this is re-implementing,
 `realtek_mst_i2c_spi_wait_command_done(fd, MCU_MODE, MCU_ISP_MODE_MASK, 0, 1);`
