This series blows up the build for me, are you sure you tested it?

drivers/tty/serial/samsung_tty.c: In function ‘s3c64xx_serial_handle_irq’:
drivers/tty/serial/samsung_tty.c:948:45: error: passing argument 1 of ‘s3c24xx_serial_rx_irq’ discards ‘const’ qualifier from pointer target type [-Werror=discarded-qualifiers]
  948 |                 ret = s3c24xx_serial_rx_irq(ourport);
      |                                             ^~~~~~~
drivers/tty/serial/samsung_tty.c:856:68: note: expected ‘struct s3c24xx_uart_port *’ but argument is of type ‘const struct s3c24xx_uart_port *’

And so on...
