Subject: [PATCH 1/2] genirq: Set IRQCHIP_SKIP_SET_WAKE flag for dummy_irq_chip
Date: Tue,  5 May 2015 18:19:52 +0200	[thread overview]
Message-ID: <1430843001-9945-2-git-send-email-mingo@kernel.org> (raw)
In-Reply-To: <1430843001-9945-1-git-send-email-mingo@kernel.org>

From: Roger Quadros <rogerq@ti.com>

Without this system suspend is broken on systems that have
drivers calling enable/disable_irq_wake() for interrupts based off
the dummy irq hook. (e.g. drivers/gpio/gpio-pcf857x.c)
