[PATCH 1/6] perf tools: Fix hist_entry__filter() for hierarchy

Show all headers | View raw

When hierarchy mode is enabled each output format is in a separate hpp
list.  So when applying filter it should check all formats in the list.
Currently it only checks a single ->fmt field which was not set properly.
