The 'wakeup_enabled' variable in this driver is only accessed by the optional power management functions and we get a warning when they are disabled:
drivers/power/collie_battery.c:29:12: error: 'wakeup_enabled' defined but not used [-Werror=unused-variable] This moves the definition next to the users inside the same #ifdef, which avoids the warning.
