We get a harmless build warning when trying to use the mediatek DRM driver with IOMMU support disabled: warning: (DRM_MEDIATEK) selects IOMMU_DMA which has unmet direct dependencies (IOMMU_SUPPORT) However, the IOMMU_DMA symbol is not meant to be used by drivers at all, and this driver doesn't seem to have a strict dependency on it other than using the mediatek IOMMU driver that does. Since we also want to be able to do compile tests with the driver on other platforms, the IOMMU_DMA symbol should not be selected here. Signed-off-by: Arnd Bergmann <arnd@xxxxxxxx> --- If someone has a better explanation about why the 'select' is here, let me know, it certainly seems out of place. drivers/gpu/drm/mediatek/Kconfig | 1 - 1 file changed, 1 deletion(-) diff --git a/drivers/gpu/drm/mediatek/Kconfig b/drivers/gpu/drm/mediatek/Kconfig index 0c06a69d7f04..545973f6b743 100644 --- a/drivers/gpu/drm/mediatek/Kconfig +++ b/drivers/gpu/drm/mediatek/Kconfig @@ -7,7 +7,6 @@ config DRM_MEDIATEK select DRM_KMS_HELPER select DRM_MIPI_DSI select DRM_PANEL - select IOMMU_DMA select MEMORY select MTK_SMI help -- 2.7.0 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
