[SRU][G/linux-oracle][PATCH 10/18] perf/arm_dmc620_pmu: Fix error return code in dmc620_pmu_device_probe()

[Khalid Elmously]

From: Wei Yongjun <weiyongjun1 at huawei.com>

BugLink: https://bugs.launchpad.net/bugs/1925421

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