From 49bddc73d15c25a68e4294d76fc74519fda984cd Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Wed, 7 Aug 2019 09:30:29 +0530 Subject: [PATCH] libnvdimm/of_pmem: Provide a unique name for bus provider ndctl binaries, v66 and older, mistakenly require 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.
