[PATCH] mmc: aspeed: move kunit test into separate module
From: Arnd Bergmann <arnd@kernel.org>
Date: 2021-01-25 12:44:09
Also in:
linux-arm-kernel, linux-mmc, lkml, openbmc
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
From: Arnd Bergmann <arnd@arndb.de> Having both the driver and the unit test in the same module leads to a link failure because of the extra init/exit functions: drivers/mmc/host/sdhci-of-aspeed-test.c:98:1: error: redefinition of '__inittest' kunit_test_suite(aspeed_sdhci_test_suite); Make it a separate module instead.
