Subject: [PATCH 2/2] perf tools: use PTR_ERR_OR_ZERO inetead of return code
Date:   Fri,  7 Sep 2018 09:34:42 +0800
Message-Id: <1536284082-23466-2-git-send-email-dingxiang@cmss.chinamobile.com>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

use PTR_ERR_OR_ZERO for bpf__setup_stdout return code,
it looks better.
