Subject: [PATCH 25/28] perf cs-etm: Remove errnoeous ERR_PTR() usage in cs_etm__process_auxtrace_info
Date: Mon, 15 Jul 2019 18:11:57 -0300	[thread overview]
Message-ID: <20190715211200.10984-26-acme@kernel.org> (raw)
In-Reply-To: <20190715211200.10984-1-acme@kernel.org>

From: YueHaibing <yuehaibing@huawei.com>

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_info
return -ENOMEM instead.
