File 0003-nvme-print-Show-paths-from-the-first-namespace-only.patch of Package nvme-cli.26914

From: Daniel Wagner <dwagner@suse.de>
Date: Wed, 25 May 2022 17:33:08 +0200
Subject: nvme-print: Show paths from the first namespace only
Git-commit: 7435ed9ae6a66fa3f7f5d5164bc727c73aed6759
References: bsc#1200044 bsc#1199956 bsc#1199990

When listing the subsystem, show the path from the first namespace
only. Every namespace has the same paths for a subsystem. This avoids
listening the same controllers for each namespace.
