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.
