Subject: [PATCH v4 04/16] block: sed-opal: close parameter list in cmd_finalize
Date: Fri, 1 Feb 2019 21:50:11 +0100 [thread overview]
Message-ID: <1549054223-12220-5-git-send-email-zub@linux.fjfi.cvut.cz> (raw)
In-Reply-To: <1549054223-12220-1-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.
