From 61e015ac5b4d46c2054a78d9bc82c840274929a0 Mon Sep 17 00:00:00 2001 From: Varun Sethi Date: Tue, 23 Apr 2013 10:05:24 +0530 Subject: iommu: Move swap_pci_ref function to drivers/iommu/pci.h. The swap_pci_ref function is used by the IOMMU API code for swapping pci device pointers, while determining the iommu group for the device. Currently this function was being implemented for different IOMMU drivers. This patch moves the function to a new file, drivers/iommu/pci.h so that the implementation can be shared across various IOMMU drivers.
