Review Comment:
Because it's only needed in SMP version to workaround `uart_xmitchars` in
`serial_io.c`, for non SMP there is already whole section critical. We can
make it more readable like this, what you think?
```c
# ifdef CONFIG_SMP
spin_unlock_irqrestore(&priv->lock, flags);
uart_xmitchars(dev);
flags = spin_lock_irqsave(&priv->lock);
# else
uart_xmitchars(dev);
# endif
```
