Randy found that with the following Kconfig settings we have duplicate definitions (e.g. __inittest()) in sdhci-of-aspeed due to competing module_init()/module_exit() calls from kunit and driver the itself. ``` CONFIG_MMC_SDHCI_OF_ASPEED=m CONFIG_MMC_SDHCI_OF_ASPEED_TEST=y ``` Conditionally open-code the kunit initialisation to avoid the error.
