If there was an error, then probably the one bringing warning and wrong kconfig option (6ae5343c26f9cba5e9ef8 "iommu/exynos: update to use iommu big-endian")?

Since we print the correct warning, an allmodconfig build is no longer clean but always prints it, which defeats compile-testing: drivers/iommu/exynos-iommu.c:58:2: error: #warning "revisit driver if we can enable big-endian ptes" [-Werror=cpp] This replaces the #warning with a dependency, moving warning text into a comment.
