tools/power/x86/intel_pstate_tracer: Fix non root execution for post processing a trace file
This script is supposed to be allowed to run with regular user privileges if a previously captured trace is being post processed. Commit fbe313884d7d (tools/power/x86/intel_pstate_tracer: Free the trace buffer memory) introduced a bug that breaks that option. Commit 35459105deb2 (tools/power/x86/intel_pstate_tracer: Add optional setting of trace buffer memory allocation) moved the code but kept the bug. This patch fixes the issue. Fixes: 35459105deb2 (tools/power/x86/intel_pstate_tracer: Add optional ...) Signed-off-by: Doug Smythies <dsmythies@telus.net> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
