[PATCH 25/42] perf cs-etm: Remove errnoeous ERR_PTR() usage in in cs_etm__process_auxtrace_info

From: YueHaibing
Date: Thu Mar 14 2019 - 22:26:49 EST


intlist__findnew() doesn't uses ERR_PTR() as a return mechanism so its callers
shouldn't try to extract the error using PTR_ERR(ret-from-intlist__findnew()),
make cs_etm__process_auxtrace_info9) return -ENOMEM instead.
