+Subject: [PATCH] Fix mismatch of OpenSSL function signatures that cause errors
+ with gcc-14
+
+Building with gcc-14 fails with diagnostics like this:
+
+```
+src/tpm2-tss-engine-rsa.c:805:46: error: passing argument 2 of 'EVP_PKEY_meth_set_copy' from incompatible pointer type [-Wincompatible-pointer-types]
+  805 |     EVP_PKEY_meth_set_copy(pkey_rsa_methods, rsa_pkey_copy);
+      |                                              ^~~~~~~~~~~~~
+      |                                              |
+      |                                              int (*)(EVP_PKEY_CTX *, EVP_PKEY_CTX *) {aka int (*)(struct evp_pkey_ctx_st *, struct evp_pkey_ctx_st *)}
+/usr/include/openssl/evp.h:2005:36: note: expected 'int (*)(EVP_PKEY_CTX *, const EVP_PKEY_CTX *)' {aka 'int (*)(struct evp_pkey_ctx_st *, const struct evp_pkey_ctx_st *)'} but argument is of type 'int (*)(EVP_PKEY_CTX *, EVP_PKEY_CTX *)' {aka 'int (*)(struct evp_pkey_ctx_st *, struct evp_pkey_ctx_st *)'}
+```
+
+A look into OpenSSL upstream shows that these functions have always had const
+`src` parameters. Thus this error was simply not detected by earlier compiler
+versions.
