Ingo Molnar 55632770d7 perf events: Fix false positive build warning with older GCC's ... gcc 4.2.1 produces: util/probe-event.c: In function 'add_perf_probe_events': util/probe-event.c:883: warning: 'tev' may be used uninitialized in this function make: *** [util/probe-event.o] Error 1 Newer GCCs get this right. To work it around, initialize the variable to NULL so that older GCCs see it as initialized too.
