genksyms: add printf format attribute to error_with_pos()
When compiling with -Wsuggest-attribute=format in HOSTCFLAGS, gcc complains that error_with_pos() may be declared with a printf format attribute: scripts/genksyms/genksyms.c:726:3: warning: function might be possible candidate for ‘gnu_printf’ format attribute [-Wsuggest-attribute=format] vfprintf(stderr, fmt, args); ^~~~~~~~ This would allow catching printf-format errors at compile time in callers to error_with_pos(). Add this attribute. Signed-off-by: Nicolas Iooss <nicolas.iooss_linux@m4x.org> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
