    perf evsel: Propagate error info from tp_format · 8dd2a131
    Jiri Olsa authored
    Propagate error info from tp_format via ERR_PTR to get it all the way
    down to the parse-event.c tracepoint adding routines. Following
    functions now return pointer with encoded error:
    
      - tp_format
      - trace_event__tp_format
      - perf_evsel__newtp_idx
      - perf_evsel__newtp
    
    This affects several other places in perf, that cannot use pointer check
    anymore, but must utilize the err.h interface, when getting error
    information from above functions list.
