From b9997e385eb2b9004d989e3710bd9001532410c0 Mon Sep 17 00:00:00 2001 From: Sudeep Dutt Date: Sun, 18 Oct 2015 20:54:37 -0700 Subject: [PATCH] iommu/vt-d: Use dev_err(..) in intel_svm_device_to_iommu(..) This will give a little bit of assistance to those developing drivers using SVM. It might cause a slight annoyance to end-users whose kernel disables the IOMMU when drivers are trying to use it. But the fix there is to fix the kernel to enable the IOMMU.
