You removed global function, but still left declaration and calling...

arch/mips/mti-malta/malta-init.c:
setup_early_serial8250_console(console_string);
drivers/firmware/pcdp.c:        return setup_early_serial8250_console(options);
include/linux/serial_8250.h:extern int
setup_early_serial8250_console(char *cmdline);
