Subject: [EXT] [PATCH v2 34/44] crypto/mvsam: fix segment fault when parse
devargs
External Email
----------------------------------------------------------------------
The rte_kvargs_process() was used to parse KV pairs, it also supports to parse
'only keys' (e.g. socket_id) type. And the callback function parameter 'value'
is NULL when parsed 'only keys'.
This patch fixes segment fault when parse input args with 'only keys'.
Fixes: 25b05a1c806b ("crypto/mvsam: parse max number of sessions")
