No, that's not what this patch is doing. Maybe you could enlighten me
how priv->params could ever be NULL when that is _not_ a pointer? That's
completely impossible as it isn't a pointer.
If you tried "priv->params = NULL" the C compiler would barf on it.
I suspect you've misunderstood the code, and this change isn't actually
necessary.
