Subject: [PATCH 4.14 039/217] drivers/perf: xgene_pmu: Fix IOB SLOW PMU parser error

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Hoan Tran <hoan.tran@...erecomputing.com>

[ Upstream commit a45fc268db20ecd859bb61e25045912b3194b5e6 ]

This patch fixes the below parser error of the IOB SLOW PMU.

        # perf stat -a -e iob-slow0/cycle-count/ sleep 1
        evenf syntax error: 'iob-slow0/cycle-count/'
                                 \___ parser error

It replaces the "-" character by "_" character inside the PMU name.
