From f4e209cdc7a00f934007f40cf885471799073b0d Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Tue, 8 Sep 2015 19:00:35 +0200 Subject: irqchip/renesas-intc-irqpin: Propagate wake-up settings to parent The renesas-intc-irqpin interrupt controller is cascaded to the GIC, but its driver doesn't propagate wake-up settings to the parent interrupt controller. Since commit aec89ef72ba6c944 ("irqchip/gic: Enable SKIP_SET_WAKE and MASK_ON_SUSPEND"), the GIC driver masks interrupts during suspend, and wake-up through gpio-keys now fails on r8a7740/armadillo and sh73a0/kzm9g. Fix this by propagating wake-up settings to the parent interrupt controller. There's no need to handle irq_set_irq_wake() failures, as the renesas-intc-irqpin interrupt controller is always cascaded to a GIC, and the GIC driver always sets SKIP_SET_WAKE since the aforementioned commit.
