Subject: [PATCH v2 06/30] perf/amlogic: Assign parents for event_source devices
Date: Fri, 12 Apr 2024 17:10:33 +0100 [thread overview]
Message-ID: <20240412161057.14099-7-Jonathan.Cameron@huawei.com> (raw)
In-Reply-To: <20240412161057.14099-1-Jonathan.Cameron@huawei.com>
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.
