From 7bf75431a9ba1b3c2ededbcf08dca023786337fc Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Fri, 12 Apr 2024 17:10:43 +0100 Subject: perf/arm_pmu: Assign parents for event_source devices Currently the PMU device appears directly under /sys/devices/ Only root busses should appear there, so instead assign the pmu->dev parent to be the platform device.
