dev_printk() prints the value of dev_name() and handles the NULL case,
so this could be changed to:
dev_err(uport->dev, "%s%d: Unable to drain transmitter\n",
drv->dev_name,
drv->tty_driver->name_base + uport->line);
It might also be possible to remove drv->dev_name since dev_printk()
also prints the driver string, but I don't know if they are equivalent
in this case.

Same here.
