[PATCH 24/32] perf/arm-smmuv3: Assign parents for event_source device

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.
