6.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Li Zhijian <lizhijian@xxxxxxxxxxx>
[ Upstream commit 1c987cf22d6b65ade46145c03eef13f0e3e81d83 ]
Before this error path, cxlr_pmem pointed to a kzalloc() memory, free
it to avoid this memory leaking.
Fixes: f17b558d6663 ("cxl/pmem: Refactor nvdimm device registration, delete the workqueue")
