Subject: [PATCH v2 3/4] tools/bootconfig: Fix to return 0 if succeeded to show the bootconfig
Date: Tue, 16 Jun 2020 19:14:25 +0900
Message-ID: <159230246566.65555.11891772258543514487.stgit@devnote2> (raw)
In-Reply-To: <159230243779.65555.11413773790099102781.stgit@devnote2>

Fix bootconfig to return 0 if succeeded to show the bootconfig
in initrd. Without this fix, "bootconfig INITRD" command
returns !0 even if the command succeeded to show the bootconfig.

Fixes: 950313ebf79c ("tools: bootconfig: Add bootconfig command")
