Previously we had this:
if (wakeup)
ret = enable_irq_wake(...);
if (!wakeup || ret)
...
"ret" is only evaluated when "wakeup" is true, and it is always initialized
in that case, but gcc isn't smart enough to figure that out and warns:
drivers/pci/pcie/pme.c:414:14: warning: 'ret' may be used uninitialized in this function [-Wmaybe-uninitialized]
Restructure the code slightly to make it easier for gcc (and maybe for
humans as well).
