Subject: compress/qat: fix lacking memzone lookup
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=dde9cc6f6c63da04407328f24bc7721910504592;p=dpdk.git

compress/qat: fix lacking memzone lookup

Because capability memzone of compression does not have lookup
call, second and subsequent devices cannot be created.

Fixes: 7788dceccb80 ("common/qat: add multi-process handling of capabilities")
