Leo Yan 4fe7ea29e4 perf hists browser: Fix potential NULL pointer dereference found by the smatch tool ... [ Upstream commit ceb75476db ] Based on the following report from Smatch, fix the potential NULL pointer dereference check. tools/perf/ui/browsers/hists.c:641 hist_browser__run() error: we previously assumed 'hbt' could be null (see line 625) tools/perf/ui/browsers/hists.c:3088 perf_evsel__hists_browse() error: we previously assumed 'browser->he_selection' could be null (see line 2902) tools/perf/ui/browsers/hists.c:3272 perf_evsel_menu__run() error: we previously assumed 'hbt' could be null (see line 3260) This patch firstly validating the pointers before access them, so can fix potential NULL pointer dereference.
