If serial console wake-up is enabled ("echo enabled > /sys/.../ttySC0/power/wakeup"), and any serial input is received while the system is suspended, serial port input no longer works after system resume. Note that: 1) The system can still be woken up using the serial console, 2) Serial port input keeps working if the system is woken up in some other way (e.g. Wake-on-LAN or gpio-keys), and no serial input was received while suspended. To fix this, replace SET_LATE_SYSTEM_SLEEP_PM_OPS() by SET_NOIRQ_SYSTEM_SLEEP_PM_OPS(), as the callbacks installed by the former happen too early resp. late in the suspend resp. resume process.
