From 1b7718fcc3f20f89931a4cf6a4fde2546cf143bd Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Fri, 12 Apr 2024 17:10:33 +0100 Subject: [PATCH] perf/amlogic: 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.
