[ Upstream commit 0258502f11a4f6036b5f8b34b09027c8a92def3a ]

drivers/tty/serial/cpm_uart/cpm_uart_core.c: In function ‘cpm_uart_init_port’:
drivers/tty/serial/cpm_uart/cpm_uart_core.c:1251:7: error: ‘udbg_port’ undeclared (first use in this function); did you mean ‘uart_port’?
  if (!udbg_port)
       ^~~~~~~~~
       uart_port

commit d142585bceb3 leave this corner, wrap it with #ifdef block
