include/linux/sprintf.h:11:54: error: unknown type name 'va_list'
   11 | __printf(2, 0) int vsprintf(char *buf, const char *, va_list);
      |                                                      ^~~~~~~
include/linux/sprintf.h:1:1: note: 'va_list' is defined in header '<stdarg.h>'; this is probably fixable by adding '#include <stdarg.h>'
