> Without CONFIG_MODULES, __init_or_module means __init, so
> serial8250_pnp_exit() and serial8250_hub6_exit() end up in .init.text.
> They are also called from serial8250_exit(), which is __exit, and
> modpost warns:
> 
>   WARNING: modpost: vmlinux: section mismatch in reference: serial8250_exit+0x2a (section: .exit.text) -> serial8250_pnp_exit (section: .init.text)
> 
> The exit code never runs in such a kernel, so nothing breaks at runtime.
> But a function that is called from both __init and __exit code can't
> carry either annotation, so drop it.
