[EXT] [PATCH 4/9] cryptodev: fix segment fault when parse input args

[Akhil Goyal]

> 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'
> (e.g. socket_id,max_nb_queue_pairs).

I would say, you can squash your 4/9 and 5/9 patch in a single commit.
As you are doing the same thing in both the patches.
