Whether or not it is a generic algorithm is irrelevant.

What is relevant is whether any other implementations exist of the
same algorithm, because in this case, the generic implementation must
be available earlier, so that it can be used for testing the other

This concern does not apply for ecrdsa, so this patch is unnecessary.
