Subject: [PATCH 06/32] perf/hisi-hns3: Assign parents for event_source device
Date: Tue, 4 Apr 2023 14:41:59 +0100 [thread overview]
Message-ID: <20230404134225.13408-7-Jonathan.Cameron@huawei.com> (raw)
In-Reply-To: <20230404134225.13408-1-Jonathan.Cameron@huawei.com>
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 PCI device.
