When building with C=1, sparse reports the following warning: net/socket.c:1735:21: warning: symbol 'update_socket_protocol' was not declared. Should it be static? The function update_socket_protocol() is defined as __weak, intended to be overwritten by architecture-specific implementations. Therefore, it cannot be static. Add a declaration in include/net/sock.h to fix this sparse warning.
