From 36a40c37389c7a1bef3f1024c55c056304acf439 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Tue, 7 Jun 2022 18:25:25 +0300 Subject: nvdimm/namespace: return uuid_null only once in nd_dev_to_uuid() Refactor nd_dev_to_uuid() in order to make code shorter and cleaner by joining conditions and hence returning uuid_null only once.
