| |
The CrystalCove GPIO irqchip doesn't have irq_set_wake callback defined so we should set IRQCHIP_SKIP_SET_WAKE for it or it would cause an irq desc's wake_depth unbalanced warning during system resume phase from the gpio_keys driver, which is the driver for the power button of the ASUS T100 laptop.
