The irq loop:
do {
iir = serial_in(up, UART_IIR);
if (iir & UART_IIR_NO_INT)
break;
...
} while (!(iir & UART_IIR_NO_INT) && max_count--);
After the if statement the variable iir is guaranteed to not have the
UART_IIR_NO_INT bit set and the remaining body of the loop doesn't re-read iir
so the check in the while is redundant.
