Compiling the driver with !CONFIG_PM_SLEEP causes following compilation warnings: drivers/tty/serial/8250/8250_dw.c:404:12: warning: ‘dw8250_suspend’ defined but not used [-Wunused-function] drivers/tty/serial/8250/8250_dw.c:413:12: warning: ‘dw8250_resume’ defined but not used [-Wunused-function] Fix this by using CONFIG_PM_SLEEP instead.
