From a0c74f6c9ea9cebd7a8f38142bf87e7c12c2905d Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Tue, 18 Jul 2023 01:28:43 +0100 Subject: platform: Provide stubs for !HAS_IOMEM builds The various _ioremap_resource functions are not built when CONFIG_HAS_IOMEM is disabled but no stubs are provided. Given how widespread IOMEM usage is in drivers and how rare !IOMEM configurations are in practical use let's just provide some stubs so users will build without having to add explicit dependencies on IOMEM. The most likely use case is builds with UML for KUnit testing.
