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.

Arnd, thanks for the patch and for your help! However, this time
Andrew already posted a similar patch [1] to fix the problem, which I
have just applied.
