The variable 'wakeup_irq' is defined within #ifdef CONFIG_PM_SLEEP_DEBUG
and used outside of it. And that breaks kernel build:
/home/viresh/linux/drivers/base/power/wakeup.c:871: undefined reference to
`wakeup_irq'
/home/viresh/drivers/base/power/wakeup.c:871: undefined reference to
`wakeup_irq'
Fix it by defining the variable outside of the ifdef.
Fixes: d1e59c235322 ("PM / sleep: Report interrupt that caused system wakeup")
