From 16d417f6c45b1854e29fc5d6de722de0bdc6ccdf Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Fri, 12 Apr 2024 17:10:30 +0100 Subject: perf/hisi-uncore: 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.
