Since all Tegra SoCs have HAS_IOMEM, the SRAM dependency was\nimplicitly satisfied for real hardware configurations.\n\nThe driver was later de-staged in commit 8bd4aaf438e3 (\"media: staging:\ntegra-vde: De-stage driver\") and relocated to\ndrivers/media/platform/nvidia/tegra-vde/ in commit 9b18ef7c9ff4 (\"media:\nplatform: rename tegra/vde/ to nvidia/tegra-vde/\"). Throughout these moves,\nthe `select SRAM` remained without a corresponding HAS_IOMEM dependency.\n\nUnder COMPILE_TEST on a hypothetical architecture without HAS_IOMEM (such\nas UML in some configurations), the select would force SRAM on without its\nHAS_IOMEM dependency being met. Add an explicit `depends on HAS_IOMEM` to\nmake the dependency chain complete and prevent this misconfiguration under\nCOMPILE_TEST.\n\nAssisted-by: Claude:claude-opus-4-6 kconfiglint\nSigned-off-by: Sasha Levin \n---\n drivers/media/platform/nvidia/tegra-vde/Kconfig | 1 +\n 1 file changed, 1 insertion(+)","diff":"diff --git a/drivers/media/platform/nvidia/tegra-vde/Kconfig b/drivers/media/platform/nvidia/tegra-vde/Kconfig\nindex 2fe13f39c95bb..f05fcc94decaf 100644\n--- a/drivers/media/platform/nvidia/tegra-vde/Kconfig\n+++ b/drivers/media/platform/nvidia/tegra-vde/Kconfig\n@@ -2,6 +2,7 @@ config VIDEO_TEGRA_VDE\n \ttristate \"NVIDIA Tegra Video Decoder Engine driver\"\n \tdepends on V4L_MEM2MEM_DRIVERS\n \tdepends on ARCH_TEGRA || COMPILE_TEST\n+\tdepends on HAS_IOMEM\n \tdepends on VIDEO_DEV\n \tselect DMA_SHARED_BUFFER\n \tselect IOMMU_IOVA\n","prefixes":[]}
