Subject: [PATCH] cxl/region: Fix cxlr_pmem leaks
Date: Sun, 28 Apr 2024 11:07:48 +0800 [thread overview]
Message-ID: <20240428030748.318985-1-lizhijian@fujitsu.com> (raw)
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")
