Subject: [PATCH v6 7/8] crypto: x86/glue_helper: Remove function prototype cast helpers
Date: Thu, 21 Nov 2019 17:03:33 -0800
Message-ID: <20191122010334.12081-8-keescook@chromium.org> (raw)
In-Reply-To: <20191122010334.12081-1-keescook@chromium.org>

Now that all users of the function prototype casting helpers have been
removed, delete the unused macros.
