perf ui/gtk: Fix segmentation fault on perf_hpp__for_each_format loop
The commit 2b8bfa6bb8a7 ("perf tools: Centralize default columns init in perf_hpp__init") moves initialization of common overhead column to perf_hpp__init() but forgot about the gtk code. So the gtk code added the same column to the list twice causing infinite loop when iterating it by perf_hpp__for_each_format loop. When I run perf report --gtk, I can see following messages indefinitely. (perf:11687): Gtk-CRITICAL **: IA__gtk_main_quit: assertion 'main_loops != NULL' failed perf: Segmentation fault Signed-off-by: Namhyung Kim <namhyung@kernel.org> Reviewed-by: Pekka Enberg <penberg@kernel.org> Cc: Andi Kleen <andi@firstfloor.org> Cc: Christoph Hellwig <hch@infradead.org> Cc: Ingo Molnar <mingo@kernel.org> Cc: Jiri Olsa <jolsa@redhat.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Pekka Enberg <penberg@kernel.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/1375766056-19377-2-git-send-email-namhyung@kernel.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
