tty: serial: sh-sci: Add default for number of ports for compile-testing
When compile-testing an allmodconfig kernel for a platform without sh-sci serial ports, the SERIAL_SH_SCI_NR_UARTS symbol of type "int" doesn't get assigned a numerical default value, but an empty string, leading to a build failure: .config:3814:warning: symbol value '' invalid for SERIAL_SH_SCI_NR_UARTS ... make[3]: *** [silentoldconfig] Error 1 Fix this by explicitly providing a default value of 2, like before. Reported-by: kbuild test robot <fengguang.wu@intel.com> Fixes: f6731485a51978ca ("tty: serial: sh-sci: Hide number of ports config question") Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
