[PATCH] libnvdimm, of_pmem: use dev_to_node() instead of of_node_to_nid()

[PATCH] libnvdimm, of_pmem: use dev_to_node() instead of of_node_to_nid()

[Rob Herring]

Remove the direct dependency on of_node_to_nid() by using dev_to_node()
instead. Any DT platform device will have its NUMA node id set when the
device is created.

With this, commit 291717b6fbdb ("libnvdimm, of_pmem: workaround OF_NUMA=n
build error") can be reverted.

Thanks Rob, we'll get this queued up for 4.17-rc2.
