I suggest to clarify this view a bit more also according to statements
like the following.
1. https://elixir.bootlin.com/linux/v6.8-rc2/source/kernel/events/core.c#L11532
perf_pmu_register:
…
pmu->name = name;
…
2. https://elixir.bootlin.com/linux/v6.8-rc2/source/kernel/events/core.c#L11472
pmu_dev_alloc:
…
ret = dev_set_name(pmu->dev, "%s", pmu->name);
…

Markus
