While we do hold the forcewake for legacy ringbuffer initialisation, we don't guard our access with the uncore.lock spinlock. In theory, we only initialise when no others should be accessing the same mmio cachelines, but in practice be safe as this is an infrequently used path and not worth risky micro-optimisations.
