You are right, I found that variable buf also don't make sense here,
maybe this could be more clear.

    param = kzalloc(sizeof(struct viawget_wpa_param), GFP_KERNEL);
    if (param == NULL)
        return -ENOMEM;

removing two unnecessary variable, buf and blen.

In this situation, I should send a new patch v2 for it base on the
previous path? or send a new patch include all changes?
