Subject: [PATCH 01/14] crypto/dpaa2_sec: fix fle buffer leak
Date: Fri, 22 Apr 2022 09:20:47 +0530	[thread overview]
Message-ID: <20220422035100.3180870-1-g.singh@nxp.com> (raw)

Driver allocates a fle buffer for each packet
before enqueue and free the buffer on dequeue. But in case if
there are enqueue failures, then code should free the fle buffers.

Fixes: b15cbf5b2d88 ("crypto/dpaa2_sec: fix fle buffer leak")
Cc: stable@dpdk.org
