Subject: [PATCH v2] genirq: Set IRQCHIP_SKIP_SET_WAKE flag for dummy_irq_chip
Date: Wed, 15 Apr 2015 11:14:11 +0300	[thread overview]
Message-ID: <552E1DD3.4040106@ti.com> (raw)
In-Reply-To: <1427721345-6402-1-git-send-email-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)
