[gregkh]

From: Greg Kroah-Hartman <gre...@linuxfoundation.org>

From: Wei Yongjun <weiyongj...@huawei.com>

[ Upstream commit c8e3866836528a4ba3b0535834f03768d74f7d8e ]

Fix to return negative error code -ENOMEM from the error handling
case instead of 0, as done elsewhere in this function.

Fixes: 53c218da220c ("driver/perf: Add PMU driver for the ARM DMC-620 memory 
controller")
