I based the patch on the fact that, on x86 at least, hardware using these variants hasn't been made for a long time. In the hopes of preserving at least part of the benefit of the patch, could you please change it to `default y if !X86_64`? > drivers/tty/serial/8250/Kconfig | 1 + > 1 file changed, 1 insertion(+) > > diff --git a/drivers/tty/serial/8250/Kconfig b/drivers/tty/serial/8250/Kconfig > index af0688156dd0..89c7ecb55619 100644 > --- a/drivers/tty/serial/8250/Kconfig > +++ b/drivers/tty/serial/8250/Kconfig > @@ -63,6 +63,7 @@ config SERIAL_8250_PNP > config SERIAL_8250_16550A_VARIANTS > bool "Support for variants of the 16550A serial port" > depends on SERIAL_8250 > + default y > help > The 8250 driver can probe for many variants of the venerable 16550A > serial port.
