| Subject: irqchip/irq-bcm7038-l1: Enable parent IRQ if necessary |
| |
| From: Florian Fainelli <f.fainelli@gmail.com> |
| |
| [ Upstream commit 27eebb60357ed5aa6659442f92907c0f7368d6ae ] |
| |
| If the 'brcm,irq-can-wake' property is specified, make sure we also |
| enable the corresponding parent interrupt we are attached to. |
