tools strfilter: Use __fallthrough
commit d64b721d27aef3fbeb16ecda9dd22ee34818ff70 upstream. The implicit fall through case label here is intended, so let us inform that to gcc >= 7: util/strfilter.c: In function 'strfilter_node__sprint': util/strfilter.c:270:6: error: this statement may fall through [-Werror=implicit-fallthrough=] if (len < 0) ^ util/strfilter.c:272:2: note: here case '!': ^~~~ cc1: all warnings being treated as errors Cc: Adrian Hunter <adrian.hunter@intel.com> Cc: David Ahern <dsahern@gmail.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Namhyung Kim <namhyung@kernel.org> Cc: Wang Nan <wangnan0@huawei.com> Link: http://lkml.kernel.org/n/tip-z2dpywg7u8fim000hjfbpyfm@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
