Subject: [PATCH] drm/exynos/dma: Drop iommu_dma_init_domain() stub
Date: Thu, 26 Mar 2026 17:30:38 +0800 [thread overview]
Message-ID: <20260326093039.1152770-1-wenst@chromium.org> (raw)
Commit 1feda5eb77fc ("drm/exynos: Use selected dma_dev default iommu
domain instead of a fake one") removed the code around creating a
custom IOMMU domain, but forgot to remove the stub.
Remove the iommu_dma_init_domain() stub as the function is no longer
referenced, and was also made private to the IOMMU DMA code.
