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.
