charset="utf-8" The Error ** argument must be NULL, &error_abort, &error_fatal, or a pointer to a variable containing NULL. Passing an argument of the latter kind twice without clearing it in between is wrong: if the first call sets an error, it no longer points to NULL for the second call. virt_machine_device_plug_cb() passes @errp to cryptodev_builtin_sym_close_session() in a loop. Harmless, because cryptodev_builtin_sym_close_session() can't actually fail. Fix by dropping its Error ** parameter.
