Subject[PATCH 1/2] platform/x86: intel_int0002_vgpio: Fix wakeups not working on Cherry Trail
Date
Commit 871f1f2bcb01 ("platform/x86: intel_int0002_vgpio: Only implement
irq_set_wake on Bay Trail") removed the irq_set_wake method from the
struct irq_chip used on Cherry Trail, but it did not set
IRQCHIP_SKIP_SET_WAKE causing kernel/irq/manage.c: set_irq_wake_real()
to return -ENXIO.

This causes the kernel to no longer see PME events reported through the
INT0002 device as wakeup events. Which e.g. breaks wakeup by the (USB)
keyboard on many Cherry Trail 2-in-1 devices.
