perf evsel: Propagate error info from tp_format
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.
