[PATCH 4.1 10/65] gpio: crystalcove: set IRQCHIP_SKIP_SET_WAKE for the irqchip

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



4.1-stable review patch.  If anyone has any objections, please let me know.

------------------

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.
