From 3a1bb75ebc1b8965c7f7dbb86584143feda8e83b Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Fri, 12 Apr 2024 17:10:34 +0100 Subject: perf/arm_cspmu: Assign parents for event_source devices Currently all these devices appear directly under /sys/devices/ Only root busses should appear there, so instead assign the pmu->dev parents to be the platform device.
