Subject: [PATCH] nvdimm/of_pmem: Provide a unique name for bus provider
Date: Wed,  7 Aug 2019 09:30:29 +0530	[thread overview]
Message-ID: <20190807040029.11344-1-aneesh.kumar@linux.ibm.com> (raw)

ndctl utility requires the ndbus to have unique names. If not while
enumerating the bus in userspace it drops bus with similar names.
This results in us not listing devices beneath the bus.
