X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=b9997e385eb2b9004d989e3710bd9001532410c0;p=deliverable%2Flinux.git 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.
