perf probe: Check if *ptr2 is zero and not ptr2 Static anaylsis with cppcheck[1] detected an incorrect comparison: [tools/perf/util/probe-event.c:216]: (warning) Char literal compared with pointer 'ptr2'. Did you intend to dereference it? Dereference ptr2 for the comparison to fix this. 1: https://sourceforge.net/p/cppcheck/wiki/Home/ Signed-off-by: Colin King <[email protected]> Cc: Alexander Shishkin <[email protected]> Cc: Masami Hiramatsu <[email protected]> Cc: Peter Zijlstra <[email protected]> Cc: Ravi Bangoria <[email protected]> Cc: Wang Nan <[email protected]> Fixes: 35726d3a4ca9 ("perf probe: Fix to cut off incompatible chars from group name") Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Arnaldo Carvalho de Melo <[email protected]> --- tools/perf/util/probe-event.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tools/perf/util/probe-event.c b/tools/perf/util/probe-event.c index fcfbef0..d281ae2 100644 --- a/tools/perf/util/probe-event.c +++ b/tools/perf/util/probe-event.c @@ -213,7 +213,7 @@ static int convert_exec_to_group(const char *exec, char **result) goto out; } - for (ptr2 = ptr1; ptr2 != '\0'; ptr2++) { + for (ptr2 = ptr1; *ptr2 != '\0'; ptr2++) { if (!isalnum(*ptr2) && *ptr2 != '_') { *ptr2 = '\0'; break;
