File 0016-fabrics-nvme-config-modify-depends-on-n-and-t-argume.patch of Package nvme-cli.26914

From: Daniel Wagner <dwagner@suse.de>

Subject: fabrics: nvme config --modify depends on -n and -t argument
Git-commit: 1021863e5daa866327cd44d9caf0743b254e6d12
References: bsc#1203204 bsc#1203163

In order to be able to modify a config we need to look it up
first. The nvme_lookup_subsystem() call will crash if we don't
provide a NQN.

The transport is needed to be able lookup a controller.
