[PATCH v2] mmc: sdhci-of-aspeed: Fix kunit-related build error
From: Andrew Jeffery <hidden>
Date: 2021-01-22 11:51:03
Also in:
linux-arm-kernel, linux-aspeed, lkml
Subsystem:
aspeed sd/mmc driver, multimedia card (mmc), secure digital (sd) and sdio subsystem, secure digital host controller interface (sdhci) driver, the rest · Maintainers:
Andrew Jeffery, Ulf Hansson, Adrian Hunter, Linus Torvalds
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.
Fixes: 7efa02a981d6 ("mmc: sdhci-of-aspeed: Add KUnit tests for phase calculations")
