From: Nicolas Ferre <nicolas.ferre@microchip.com>
[ Upstream commit 515a10a701d570e26dfbe6ee373f77c8bf11053f ]
Use the proper struct device pointer to check if the wakeup flag and wakeup source are positioned. Use the one passed by function call which is equivalent to &bp->dev->dev.parent.
It's preventing the trigger of a spurious interrupt in case the Wake-on-Lan feature is used.
