From 764d2997ec0edbb48f12e6477ccaceecd999091d Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 5 Oct 2017 14:07:22 +0200 Subject: [PATCH] drm/i915/selftests: fix check for intel IOMMU An earlier bugfix tried to work around this build failure: drivers/gpu/drm/i915/selftests/mock_gem_device.c: In function 'mock_gem_device': drivers/gpu/drm/i915/selftests/mock_gem_device.c:151:20: error: 'struct dev_archdata' has no member named 'iommu' Checking for CONFIG_IOMMU_API is not sufficient as a compile-time test since that may be enabled in configurations that have neither INTEL_IOMMU not AMD_IOMMU enabled. This changes the check to INTEL_IOMMU instead, as this is the only case we actually care about.
