Subject: [dpdk-dev] [PATCH v3 2/2] crypto/dpaa_sec: improve error handling
Date: Sun, 10 May 2020 03:52:59 +0530	[thread overview]
Message-ID: <20200509222259.22510-2-akhil.goyal@nxp.com> (raw)
In-Reply-To: <20200509222259.22510-1-akhil.goyal@nxp.com>

The return values in cases of errors were not
specified properly. With this patch appropriate
error numbers are returned.
