Dan Williams 181c78d6c1 cxl/pmem: Fix reference counting for delayed work ... commit 08b9e0ab8a upstream. There is a potential race between queue_work() returning and the queued-work running that could result in put_device() running before get_device(). Introduce the cxl_nvdimm_bridge_state_work() helper that takes the reference unconditionally, but drops it if no new work was queued, to keep the references balanced.
