Subject: [PATCH 05/16] block: sed-opal: close parameter list in cmd_finalize
Date: Thu, 14 Feb 2019 01:15:57 +0100	[thread overview]
Message-ID: <1550103368-4605-6-git-send-email-zub@linux.fjfi.cvut.cz> (raw)
In-Reply-To: <1550103368-4605-1-git-send-email-zub@linux.fjfi.cvut.cz>

Every step ends by calling cmd_finalize (via finalize_and_send)
yet every step adds the token OPAL_ENDLIST on its own. Moving
this into cmd_finalize decreases code duplication.
