Starting from 5.19 HWE kernel, this option became as dedicated module instead of being compiled into the kernel.
5.19 hwe-next also has CONFIG_SERIAL_8250_MID=m
On 5.17 it was OK
~$ uname -r
5.19.0-32-generic
$ cat /boot/config-5.19.0-32-generic | grep 8250_MID
CONFIG_SERIAL_8250_MID=m
Please make it CONFIG_SERIAL_8250_MID=y for all the future kernels.

[Impact]
CONFIG_SERIAL_8250_MID=y is required to properly use the serial console on some platforms that are using the "mid" serial driver (such as some Intel SoC platforms).
The generic kernel should build this driver statically to make sure we properly support these platforms.
[Test case]
Boot the Ubuntu generic kernel on a system that is using the "mid" serial driver (e.g, no PCI serial).
[Fix]
Enable CONFIG_SERIAL_8250_MID=y.
[Regression potential]
Kernel footprint is increased a bit with this change (around +9K), so we may see little performance regressions at boot time in really small platforms (additional memory usage is probably negligible), but it is worth it, otherwise we won't be able to properly support these platforms.
NOTE: we may want to disable this option in the could kernels and derivatives and keep it only for the generic.
