[dpdk-dev] [PATCH 1/2] lib/sched: fix return value judgment

[Min Hu (Connor)]

From: Huisong Li <lihuisong at huawei.com>

This patch fixes return value judgment when allocate memory to store the
subport profile, and releases memory of 'rte_sched_port' if code fails to
apply for this memory.

Fixes: 0ea4c6afcaf1 ("sched: add subport profile table")
