+Subject: [PATCH] crypto: use nettle ecc_curve access functions
+
+Nettle 3.5.1 has made ecc_curve definitions (nettle_secp_192r1,
+nettle_secp_224r1, nettle_secp_256r1, ...) private and forces
+users to make use of the accessor functions (nettle_get_secp_192r1,
+...) to retrieve the specific ecc_curve structs.
