Subject: [dpdk-stable] [v2 PATCH 3/8] net/ipn3ke: fix incorrect commit check logic
Date: Wed, 6 Nov 2019 19:01:58 +0000 [thread overview]
Message-ID: <20191106190203.10750-4-ktraynor@redhat.com> (raw)
In-Reply-To: <20191106190203.10750-1-ktraynor@redhat.com>
Coverity is complaining about identical code regardless of which branch
of the if else is taken. Functionally it means an error will always be
returned if this if else is hit. Remove the else branch.
CID 337928 (#1 of 1): Identical code for different branches
(IDENTICAL_BRANCHES)identical_branches: The same code is executed
regardless of whether n->level != IPN3KE_TM_NODE_LEVEL_COS ||
n->n_children != 0U is true, because the 'then' and 'else' branches
are identical. Should one of the branches be modified, or the entire
'if' statement replaced?
1506 if (n->level != IPN3KE_TM_NODE_LEVEL_COS ||
1507 n->n_children != 0) {
1508 return -rte_tm_error_set(error,
1509 EINVAL,
1510 RTE_TM_ERROR_TYPE_UNSPECIFIED,
1511 NULL,
1512 rte_strerror(EINVAL));
else_branch: The else branch, identical to the then branch.
1513 } else {
1514 return -rte_tm_error_set(error,
1515 EINVAL,
1516 RTE_TM_ERROR_TYPE_UNSPECIFIED,
1517 NULL,
1518 rte_strerror(EINVAL));
1519 }
