From 2caa48a24061b1f8e8dab43ea3292a608a15e3c9 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Thu, 24 Jan 2013 22:34:33 -0300 Subject: [PATCH] perf header: Stop using die() calls when processing tracing data The callers of this function (perf_event__process_tracing_data) already handles a negative value return as error, so just use pr_err() to log the problem and return -1 instead of panic'ing.
