Subject[PATCH v3 1/7] libnvdimm: fix memory leaks in of_pmem.c
Date
Currently, in the last error path of of_pmem_region_probe() and in
of_pmem_region_remove(), free the memory allocated by kstrdup() is
missing. Add kfree(priv->bus_desc.provider_name) to fix it.

Fixes: 49bddc73d15c ("libnvdimm/of_pmem: Provide a unique name for bus provider")
