[PATCH 05/16] block: sed-opal: close parameter list in cmd_finalize

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

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.
