serial: 8250_mid: Add missing dependency
8250_mid uses rational_best_approximation() function, so the driver needs to select CONFIG_RATIONAL option. This fixes build error when CONFIG_RATIONAL is not enabled: drivers/built-in.o: In function `mid8250_set_termios': 8250_mid.c:(.text+0x10169a): undefined reference to `rational_best_approximation' Reported-by: Randy Dunlap <rdunlap@infradead.org> Signed-off-by: Heikki Krogerus <heikki.krogerus@linux.intel.com> Acked-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
