Subject: Remove the now unused poly[] from EC_GROUP
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=69e9c1e8dc53ce635a126470faeafda49560b733;p=openbsd

Remove the now unused poly[] from EC_GROUP

This was needed for defining the multiplication over binary fields. Since
that code is gone, this is no longer needed.
