[PATCH] tty: serial: export serial_8250_warn_need_ioport
From: Arnd Bergmann
Date: Tue Oct 29 2024 - 11:28:19 EST
From: Arnd Bergmann <arnd@xxxxxxxx>
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: 7c7e6c8924e7 ("tty: serial: handle HAS_IOPORT dependencies")
Signed-off-by: Arnd Bergmann <arnd@xxxxxxxx>

The build regression is currently part of my asm-generic tree, so I've
applied this fixup on top.
