Subject: gpio: crystalcove: set IRQCHIP_SKIP_SET_WAKE for the irqchip
From: Aaron Lu <aaron.lu@xxxxxxxxx>
commit 61e749d7e1627d375156553ea0ae83c4f6bb5a9b upstream.
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.
