cpm_uart_init_portdesc() smc1_lineif() smc2_lineif() scc1_lineif() scc2_lineif() scc3_lineif() scc4_lineif() Those functions were removed by commit 0b2a2e5b7747 ("cpm_uart: Remove !CONFIG_PPC_CPM_NEW_BINDING code"). Remove stale prototypes. UART_SMC{1..2} and UART_SCC{1..4} and SCC_WAIT_CLOSING macros are not used anymore since the above commit. cpm_uart_ports[] isn't used outside cpm_uart_core.c since the same commit, so make it static. cpm_uart_init_smc() and cpm_uart_init_scc() don't need a forward declaration. FLAG_DISCARDING and IS_DISCARDING have never been used since at least 2.6.12 and the start of git repository for kernel.
