I did not run all the tests listed in /sys/kernel/debug/mmc*/*/testlist
because some of them will overwrite the data in my card but at least
the read ones completed successfully and $subject does not cause a
regression in the Exynos5250 Snow, Exynos5420 Peach Pit and Exynos5800
Peach Pi Chromebooks where I tested it.
