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]>
