From d52788b3da2750ebc617891cf260b8f8912f522b Mon Sep 17 00:00:00 2001 From: David Gow Date: Fri, 15 Jul 2022 12:03:54 +0800 Subject: [PATCH 1/2] mmc: sdhci-of-aspeed: test: Fix dependencies when KUNIT=m While the sdhci-of-aspeed KUnit tests do work when builtin, and do work when KUnit itself is being built as a module, the two together break. This is because the KUnit tests (understandably) depend on KUnit, so a built-in test cannot build if KUnit is a module. Fix this by adding a dependency on (MMC_SDHCI_OF_ASPEED=m || KUNIT=y), which only excludes this one problematic configuration. This was reported on a nasty openrisc-randconfig run by the kernel test robot, though for some reason (compiler optimisations removing the test code?)

This should be loaded when the module is, but at the moment this only happens if KUnit is built-in. Also load this when KUnit is enabled as a module: it'll not be usable unless KUnit is loaded, but such modules are likely to depend on KUnit anyway, so it's unlikely to ever be loaded needlessly.
