tty: serial: export serial_8250_warn_need_ioport

arndb · arndb · commit c0dc92144ba1 · 2024-10-29T16:39:12.000Z
The newly added function is used from a loadable module, so it has to be exported the same way as the other function in this file: ERROR: modpost: "serial_8250_warn_need_ioport" [drivers/tty/serial/8250/8250_pci.ko] undefined! Fixes: 7c7e6c8 ("tty: serial: handle HAS_IOPORT dependencies") Reviewed-by: Niklas Schnelle <schnelle@linux.ibm.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
