[PATCH v2 1/5] perf tools: Fix segfault when using -s trace_fields

From: Namhyung Kim
Date: Tue Jan 05 2016 - 05:59:36 EST


When the 'trace_fields' sort key is used explicitly for non-tracepoint
events, it'll get segfault since it assumed evsel->tp_format was set.
Skip those events in add_all_dynamic_fields().
