We decided to fix this in ndctl tool? If we go with ndctl fix, we
can drop the kernel change. Parallely I am planning to do a  fix
for papr_scm driver that will update the provider name as "papr_scm". That
way we can find out the backend driver using

:~> ndctl list -B
[
  {
    "provider":"papr_scm",
    "dev":"ndbus1"
  },
  {
    "provider":"of_pmem",
    "dev":"ndbus0"
  }
]
