Subject: [PATCH 13/14] target/tcm_loop: Avoid that static checkers warn about dead code
Date: Thu, 01 Mar 2018 22:26:31 +0000	[thread overview]
Message-ID: <20180301222632.31507-14-bart.vanassche@wdc.com> (raw)

The code under the "release:" label can only be reached after se_cmd
has been set to a non-NULL value. Hence remove the if (se_cmd) test.
Keep the else-part since calling transport_generic_free_cmd() is not
necessary for a command that has not been submitted to the core.

Reported-by: Dan Carpenter <dan.carpenter@oracle.com>
Fixes: 4d3895d5ea43 ("target/tcm_loop: Merge struct tcm_loop_cmd and struct tcm_loop_tmr")
