compress/isal: check allocation in qp setup
Checks
Commit Message
From: Yunjian Wang <wangyunjian@huawei.com>
The function rte_zmalloc() could return NULL, the return value
need to be checked.
Fixes: dc49e6aa4879 ("compress/isal: add ISA-L compression functionality")
Fixes: 7bf4f0630af6 ("compress/isal: add ISA-L decomp functionality")
