From: Joerg Roedel <redacted> There are users outside of the IOMMU code that need to call that function. Define it for !CONFIG_IOMMU_API too so that compilation does not break. Reported-by: kbuild test robot <redacted> Signed-off-by: Joerg Roedel <redacted>
Reviewed-by: Jean-Philippe Brucker <redacted> As a result drivers/gpu/host1x/hw/channel_hw.c and drivers/gpu/drm/tegra/vic.c can lose their #ifdef CONFIG_IOMMU_API
