Subject: [PATCH] gpio/crystalcove: set IRQCHIP_SKIP_SET_WAKE for the irqchip
Date: Thu, 28 May 2015 10:58:49 +0800 [thread overview]
Message-ID: <20150528025848.GA11051@aaronlu.sh.intel.com> (raw)
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.
