From fec3b217ff19978650121103d849b5889b04780a Mon Sep 17 00:00:00 2001 From: Simon Xue Date: Fri, 24 Jun 2016 10:13:26 +0800 Subject: [PATCH] iommu/rockchip: Fix devm_{request,free}_irq parameter Even though the IOMMU shares IRQ with its master, the struct device passed to {request,free}_irq is supposed to represent the device that is signalling the interrupt. This patch makes the driver use IOMMU device instead of master's device to make things clear.
