Hi all,

After merging the tty tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

ERROR: modpost: "rsa_autoconfig" [drivers/tty/serial/8250/8250_base.ko] undefined!
ERROR: modpost: "rsa_reset" [drivers/tty/serial/8250/8250_base.ko] undefined!
ERROR: modpost: "rsa_disable" [drivers/tty/serial/8250/8250_base.ko] undefined!
ERROR: modpost: "rsa_enable" [drivers/tty/serial/8250/8250_base.ko] undefined!

Caused by commit

5a128fb475fb ("serial: 8250: move RSA functions to 8250_rsa.c")

(or its neighbours)

I have used the tty tree from next-20250618 for today.
