Subject: [PATCH 04/16] block: sed-opal: close parameter list in cmd_finalize
Date: Thu, 8 Nov 2018 22:50:19 +0100	[thread overview]
Message-ID: <20190116225538.2333D6004E@linux.fjfi.cvut.cz> (raw)

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.
