[2/9] compressdev: fix segment fault when parse input args
Checks
Commit Message
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).
Fixes: ed7dd94f7f66 ("compressdev: add basic device management")
