From 4052ce07d5d7e8158dfd5c01c514b930cb689f68 Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Fri, 12 Apr 2024 17:10:50 +0100 Subject: perf/arm-spe: Assign parents for event_source device 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.
