Subject: Re: [PATCH V2 1/7] perf script: Do not call perf_event__preprocess_sample()
twice)
perf_event__preprocess_sample() is called in
process_sample_event(). Instead of calling it
again in perf_evsel__print_ip(), pass though
the resultant addr_location.

V2: removed unused 'event' parameter from perf_evsel__print_ip()
