Command 'perf record' calls: cmd_report() record__auxtrace_init() auxtrace_record__init() On s390 function auxtrace_record__init() returns random return value due to missing initialization. This sometime causes 'perf record' to exit immediately without error message and creating a perf.data file. Fix this by setting error the return code to zero before returning from platform specific functions which may not set the error code in call cases. Signed-off-by:
