[PATCH v2 1/7] iommu/rockchip: fix devm_{request,free}_irq parameter

From: Shunqian Zheng
Date: Wed Jun 08 2016 - 09:27:01 EST


From: Simon Xue <xxm@xxxxxxxxxxxxxx>

Even though the iommu shares irq with its master, using the *dev of iommu
instead of master's *dev for devm_{request,free}_irq makes things clear.
